eSKAMI: Efficient and Scalable Multi-group Key Management for Advanced Metering Infrastructure in Smart Grid

Abstract

International audienceAdvanced Metering Infrastructure (AMI) is composed of systems and networks for measuring, collecting, storing, analyzing, and exploiting energy usage related data. AMI is an enabling technology for Smart Grid (SG) and hence represents a privileged target for security attacks with potentially great damage against infrastructures and privacy. For this reason, security has been identified as one of the most challenging topics in AMI development, and designing an efficient Key Management Scheme (KMS) is one of first important steps. In this paper, we propose a new scalable and efficient key management scheme that we call Efficient and Scalable multi-group Key Management for AMI (eSKAMI) to secure data communications in an Advanced Metering Infrastructure. It is a key management scheme that can support unicast, multicast and broadcast communications based on an efficient Multi-group Key graph technique. An analysis of security and performance, and a comparision of our scheme with recently proposed schemes show that our KMS induces low storage overhead compared to existing solutions (reduction reaches 83%) without increasing the communication overhead

The Challenges of Privacy and Access Control as Key Perspectives for the Future Electric Smart Grid

“…Each communication entity needs to obtain the certified public keys from the certificate authority before the communication is initiated [53]. There has been a lot of research based on key management procedures concerning the ESG [54], [55], [56], [57], [58]. In [59] several encryption algorithms are presented, concluding to Advanced Encryption Standard (AES) algorithm as the most appropriate for ensuring security in the ESG.…”

Securing dynamic microgrid partition in the smart grid

“…Due to the openness of SG network, message authentication has vital significance for dynamic microgrid partition. Therefore, a large number of security protocols 4–29 have been designed for this purpose. All these protocols can be categorized into three types: symmetric-key-based protocols, traditional public-key-based protocols, and identity-based protocols.…”

“…Liu et al 25 proposed a key management scheme to secure both unicast and multicast communications, which is based on a trusted third party. Benmalek and Challal 24 is a key graph management approach that is an enhancement of LKH. Perrig et al 28 presented a message authentication protocol based on hash chain.…”

“…Second, different from traditional group communications, a SM in one group may need to exchange energy with SMs in other groups, resulting in high complexity of key management. Unfortunately, traditional public-key-based 4–14 and symmetric-key-based schemes 24,25,28,29 cannot fulfill the scalability feature, as discussed below: (1) traditional public-key-based schemes (i.e. schemes based on “public key infrastructure (PKI)” 30,31 ) cannot fulfill the above scalability requirement, as illustrated by the following two examples.…”

An enhanced anonymous identity‐based key agreement protocol for smart grid advanced metering infrastructure

“…Generally, key management or key establishment cryptographic protocols are used to provide a secure communication channel . There have been a large number of key establishment protocols proposed in the literature, and examples include those presented in the previous studies …”
