Abstract

Ever-growing population of people and new electronic gadgets demand huge electricity. Existing power grids mostly use non-renewable energy sources for electricity generation which is unidirectional energy flow. Aging equipments and manual meter reading, power line failure detection and power quality measurements result in lot of power losses and delays. Smart Grid assures modern, computerized and automated electricity power generation, distribution and management. It also ensures energy efficiency with quality improvement and reliability. But since it involves some kind of wired and wireless communication, there are the chances of enormous vulnerabilities. Electricity theft, authentication, authorization, trust ranking, distributed denial of service attack, man in the middle attack are the real challenges for smart grid. Cyber Security should ensure security for smart grid system with appropriate levels of trust, privacy and security. This paper puts forth the security challenges for smart grid and discusses about possible security solutions.

1 Traditional Electricity Power Grid

Today’s electric power grid system is working with traditional equipments and is using conventional techniques for power generation, transmission, distribution, and consumption. For electricity power generation large scale power plants are used which are mainly running with non-renewable energy sources like gas, oil, coal, nuclear, hydro plants, etc. The power generation plants using coal, oil and nuclear emit hazardous gases which adds to the pollution levels to the environments. These power plants are based on the centralized approach. These power plants are usually located far away from the residential zones due to the danger of hazards. These conventional power generation mechanisms are lacking in the scalability, due to which there are limitations on the connections to be provided. Also, it does not involve the use of cooperation strategies.

For power transmission lines, there is least priority for the special requests made on telephone because it is difficult for the traditional electricity system to reroute the power to other territorial zones. On the distribution front, the present power grid has very much limited monitoring and control resources because of manual operations. Due to the sluggish local monitoring and control mechanisms, the whole system has become less efficient. Present metering infrastructure contains old meters which do not facilitate any communications with the central entities. Also, it involves manual meter readings which have lot of system flaws. On the power consumption side, the load adjustment is done manually which contains delays and inefficiencies. The important tasks such as power quality management, power failure searches, and power supply restoration are to be performed manually. This results in low data rate communication system which is prone to vulnerabilities and various attacks. Traditional electricity power grid system is depicted in Figure 1(a). Power flow in the conventional system is unidirectional from power generation plans to the consumers. The old equipments and power line infrastructure is prone to the additional power losses. It ultimately affects the overall power quality and availability of the electricity power in the emergency situations [1].

2 Smart Grid

Smart Grid has come up with the combination of the renewable energy sources like solar and wind energy with the conventional non-renewable energy sources such as coal, oil, gas, nuclear and hydro power generation plants. Smart grid encourages the extended penetration of small scale power generation plants. The whole structure of electricity power generation is highly distributed in nature. Consumer centric approach is introduced with the smart grid that ensures the small scale power generation power plants to be located close to the consumers. Smart grid also ensures reduction in greenhouse gases with major usage of renewable energy sources. Each and every entity of smart grid is to be controlled and connected with the data communication networks. The emergency electricity routing requests can be submitted through the broadband connections. With the use of intelligent software, such electricity reroute requests can be handled automatically. Also power flow can be balanced appropriately with the computerized smart grid with great ease.

Demand and supply ratios can be well-adjusted with the automation in smart grid. Grid status and power quality knowledge can be maintained and updated. Manual control and monitoring gets replaced with modern and automated systems for fault location searching, isolation provision and broken service restoration. Traditional unidirectional meters are replaced with bidirectional communication facilitating smart meters which can help in optimized monitoring and control of overall system from generation, transmission to distribution. Automated meter reading with the wireless communication aids is possible. It results into overall cost reduction with energy efficiency. Smart sensors and controllers with advanced and high speed communication infrastructure will surely maintain the optimized and uninterrupted power flow from generation to consumption sites [1]. Heterogeneous nature and self-healing capabilities of smart grid is going to be a great revolution for mankind. As illustrated in Figure 1(b), smart grid assures more automated, flexible and cost effective electricity flow from generation plants to consumer utilities. Consumer is facilitated to store the electricity when the costs are less and make use of it later or sell when the costs are relatively more. This kind of duplex service was lacking in traditional power grids. Smart Grid is a perfect blend of non-renewable energy sources with renewable energy sources for power generation, transmission, distribution with various modern data communication networks.

3 Security Threats to Smart Grid

Emerging Smart Grid is nothing but the intelligent and interconnected version of electricity power distribution network. Main goals of Smart Grid are to improve quality, efficiency and reliability in the generation and distribution of electricity, to support green information and communication technology (ICT) by reducing pollution effect through power grid, and to facilitate consumers to optimize their energy consumption. Various possible attacks at each stage of Smart Grid are depicted in Figure~2. Corresponding to the necessary security goals, three high level security objectives are taken into consideration such as availability, integrity and confidentiality. Availability ensures timely and reliable access to the smart grid for the use of necessary information. Lack of availability may lead in deflation of the power delivery activities. Integrity guarantees the authenticity and non-denial of the important information. Loss of integrity may result in the incorrect power management decisions. Confidentiality safeguards authorization of the private and proprietary information. Secret information should not be disclosed to individual users or public [2]

3.1 Smart Grid Infrastructure

Smart Grid infrastructure is a combination of various physical and cyber systems as depicted in Figure 3. From electricity power generation, distribution till consumption, it makes use of various wired and wireless networks such as Zigbee, PLC, Z-wave, IEEE 802.11, WiMAX, etc. [3]. These physical and cyber systems have different security threats such as electricity thefts, BOTNETs, data mining threats, threats to SCADA control system, online billing transaction threats, cloud computing faults, incident handling threats, information security threats, etc. it is very much essential to take into account the possible threat related to each and individual interface and design robust security solution for it. Different privacy related issues are there which can lead to the loss of trust of the consumers. Integrated cyber physical security solutions are very much necessary to bring the smart grid vision into reality. Convergence of wired and wireless services with heterogeneous security approach is needed to be developed.

Smart Grid suffers from various security issues. State of the art cyber physical security issues for smart grid are summarized in Table 1. Various parameters such as false data injection, survivability to intrusions, end to end access control and protection, delay sensitivity, power quality and voltage issues over long distance transmissions are considered here with different mechanisms for respective issue.

Estimation and decision techniques from information theory are found to be appropriate for various threats and other issues. Quality, reliability and efficiency are the basic requirements from the end users. User centric approaches are in much demand due to forthcoming user centric fifth generation (5G) communication technology. Privacy and trust are the major concerns from the consumer point of view. Green ICT standards are needed to be adopted while designing security protocols for each interface of the Smart Grid. Large scale storage capability with proper security measures is the essence of next generation social economy. Plug in hybrid electric vehicles can greatly save fuel consumption with the reduction in atmospheric pollution levels. Sensors are the tiny entities with limited battery, memory and computing capabilities. For such sensors, light weight security solutions are needed. Controllers should be redesigned with intelligence embedded into them. Present power grid system involves large amount of delays in almost every stage from generation, transmission, distribution, to consumption. Modernized Smart Grid ensures delay reduction with the help of automation techniques with smart objects with Internet of Things (IoT) and Machine to Machine Communication (M2M).

3.2 Smart Controllers with SCADA

Smart grid physical infrastructure design considers parameters such as power interruptions, quality of power and voltage related issues. Cyber infrastructure consists of communication network and supervisory control and data acquisition (SCADA) for control and reliable data communication. SCADA control center is supposed to monitor safety, reliability, secure exchange of data with high-speed, etc. Smart grid infrastructure is complex and critical therefore it can be easily targeted by attackers by introducing malicious software for interruption in power or manipulation in data. Security is major concern in smart grid. For security system designer, it is important to understand three key concepts confidentiality, integrity, and availability (CIA). For providing security tools such as authentication, authorization, and nonrepudiation can be used. Smart grid communication is bidirectional communication system therefore flow is bidirectional i.e., from control center to customer and customer to control center.

Smart grid infrastructure consists of physical infrastructure for transmission of electricity and communication network infrastructure for providing communication and control. Complexity of smart grid increases due to communication system formed by combination of hardware and software, therefore security of this system is critical issue. Attacker can attack on information and introduces false data in measurements in smart meter. For control and monitoring of critical infrastructures smart grid system uses Supervisory Control and Data Acquisition (SCADA) systems as shown in Figure 4. Control network is connected to consumer network using standard protocols such as TCP/IP therefore system is vulnerable tothreats [46].

Figure 4 Smart grid infrastructure with SCADA.

The attacks on routing protocols may disrupt the complete logical connectivity among the smart grid entities. The security protocols must be designed considering the requirements of different modules of AMI communication network such as Home Area Network (HAN), Neighbourhood Area Network (NAN) and Wide Area Network (WAN) serving numerous applications of smart grid. Thus a secured framework for routing protocols presents a promising solution for the security of the advance metering infrastructure (AMI) communication system. Secure Data Aggregation is also good method for security. The data aggregation presents one possible solution to address the constraints of low processing and storage capability of AMI system components and low bandwidth capacity of AMI wireless networks module. It takes the advantage of small sized packets traversing from smart meter nodes to the control center via tree network topology. Aggregation can be performed using a number of potential techniques such as concatenating several packets under a common header or applying an aggregation function like sum, average etc. Hence it reduces the transmission overheads by eliminating the identical header information. While carrying out secure data aggregation, the protection for confidentiality of aggregated packets must be taken into account as they contain a large volume of sensitive information. Bartoli et al. in his research work in [17] has proposed a lossless aggregation protocol for AMI communication system while maintaining both per hop as well as end to end security.

For the successful evolution of smart grid, secure and reliable communication architecture is going to the most crucial role. Moreover, the AMI network involves the transmission of real-time power related information for the management of complex power system which requires on-time and accurate message delivery. A secure network architecture design must emphasize on providing reliable end-to-end communication, strong network topology, secure forwarding, and Denial of Service (DOS) and jamming defense to alleviate attacks and attain high availability. Wenye and Zhuo provide a review on two proposed secure network architectures that include trust computing based architecture and role based network architecture. Thus, it has been observed that any single security scheme cannot address the entire security issues of AMI and also being cost effective at the same time [2].

3.3 Advanced Metering Infrastructure (AMI)

Advanced metering infrastructure (AMI) is an architecture for programmed and bidirectional cooperative communication between a smart utility meter with an IP address and a utility company. The purpose of an AMI is to provide service to service providers with real-time data of meter reading measurements to calculate power utilization by consumer.

Consumers can also get information about energy usage and billing information at any time. This information is shared via complex communication network therefore, eavesdropper can attack to hack information or to modify measured data. There are three primary threats to AMI: customer attacks, insider attacks, and terrorist or nation-wise attacks. These threats of cyber security result in loss of integrity and availability to the AMI system or to the bulk electric grid controls. System impacts range from increased peak usage up to widespread outages. AMI attacks could cause low to moderate local and regional consequences as a result of the system impacts. The risk of national harm is low to moderate but will increase as AMI market penetration increases. The lowest level highest probability threat to AMI implementations is the modification in measured consumer meter reading. Next threat with high probability is the insider attack whose motivation is financial. After The threats by international groups or terrorist groups are high levels with low-probability threats.

Figure 5 shows benefits of AMI [18]. AMI is beneficial for both consumers and electric power utility system. For the electric power utility system, AMI can perform some operations such as meter reading, power outage detection and diagnostics remotely. Consumers can easily get awareness about their energy usage with better quality and accuracy. With AMI, power failure issues can be solved very quickly.

Advanced Metering Infrastructure plays vital role in real time monitoring of Smart bidirectional information flow of power related information i.e. smart metering data and control messages. Smart Grid network is vulnerable to many cyber threats and attacks which could result in unreliable system performance. Appropriate security technique is required to deal with cyber security concerns. Table 2 shows state of the art security methodologies for AMI.

*Reliability = R, Scalability = S, Efficiency = E, Privacy = P, Latency = L, Low Latency = LL.

Intelligent Smart Grid should provide reliability, efficiency, scalability, privacy and security. But from the Table, it is clear that it provides reliability, efficiency, scalability but the performance degrades due to lack of privacy and security provisions.

Cyber security properties and approaches to be used in AMI are elaborated in Table 3 below [29].

3.4 Smart Meters

For periodic measurements of electricity consumption and regular communication of this information to power grid for record and billing purposes, the smart meters are used. Smart meter ensures two way communications between consumer meter and power grid central system. Table 4 summarises the possible attacks on smart meter and the probable security solutions for the respective attacks [30].

4 Secure Metering Schemes

The advanced metering infrastructure provides the competent and secure metering schemes. For security purpose, many researchers use cryptographic techniques, secure function evaluation technique, threshold cryptography and secret sharing technique. Following are different techniques for security in metering scheme.

The general framework for a secure metering scheme contains following things as shown in Figure 6.

Figure 6 General secure metering scheme.

Followings are the different techniques which are used for security purpose in advanced metering infrastructure.

  1. Key Management Scheme (KMS) Cryptographic algorithms are chosen for key generation.
  2. Identity based cryptography (ID based authentication protocol).
  3. Probabilistic asymmetric key encryption algorithm.
  4. Scalable Key Management (SKM) scheme by combining identity based cryptosystem and efficient key tree technique.
  5. Physically Unclonable Function (PUF) technology hardware based.
  6. Authenticated symmetric encryption algorithm.

KMS is used to solve the problem of security in smart meters but still it is not able to solve all the problems. ID based authentication protocols which provide source authentication, data integrity, non-repudiation services, confidentiality and privacy. Probabilistic asymmetric key encryption algorithm provides good confidentiality, privacy and integrity. SKM scheme provides efficiency in computation, reduces communication cost, more flexibility. PUF provides confidentiality and integrity.

5 Conclusions and Future Scope

For the security of cyber physical systems in smart grid, control and security technique co-designs are in huge demand. Overall interfaces in the smart grid system are needed to be developed with utmost care. Electricity power generation units with renewable or non-renewable energy sources, power transmission, distribution to substations and till consumer smart meters, every interface is of great importance. Electricity smart grid system as whole is closely associated with consumers for household appliances, business customers or other office infrastructures consist of large amount of database related to personal information of the consumers. This leads to various privacy concerns. Strong countermeasures are necessary to battle these security breaches against consumer trust and privacy. Researchers have lot of research opportunities and directions with the security issues and features provided in this paper.
