Performance Analysis of Certificate Renewal Scheme for AMI Networks

Abstract— Public-key cryptography is indispensable for securing the communications in Advanced Metering Infrastructure (AMI) networks. However, few works have studied the efficient use of public key cryptography certificates in such a network and most of them focus on certificates' revocation. In this paper, we extensively investigate the performance our previous proposal on an efficient certificate renewal scheme that we proposed for AMI networks. First, quantitative analysis is carried out to compare our scheme against signature-based certificate renewal schemes. Then, all schemes are implemented in a realistic network model using NS-3 to evaluate their performance. Simulation results demonstrate the improved performance of our scheme in computational cost, communication overhead, end-to-end delay, packet delivery ratio, and required bandwidth compared with the signature-based certificate renewal scheme.

Index Terms— Public key management system, certificate renewal, smart grid communication security, authentication, authorization, and access control.
