Comprehensive Evaluation on an ID-Based Side-Channel Authentication with FPGA-Based AES

Abstract

Various electronic devices are increasingly being connected to the Internet. Meanwhile, security problems, such as fake silicon chips, still exist. The significance of verifying the authenticity of these devices has led to the proposal of side-channel authentication. Side-channel authentication is a promising technique for enriching digital authentication schemes. Motivated by the fact that each cryptographic device leaks side-channel information depending on its used secret keys, cryptographic devices with different keys can be distinguished by analyzing the side-channel information leaked during their calculation. Based on the original side-channel authentication scheme, this paper adapts an ID-based authentication scheme that can significantly increase the authentication speed compared to conventional schemes. A comprehensive study is also conducted on the proposed ID-based side-channel authentication scheme. The performance of the proposed authentication scheme is evaluated in terms of speed and accuracy based on an FPGA-based AES implementation. With the proposed scheme, our experimental setup can verify the authenticity of a prover among 2 70 different provers within 0.59 s; this could not be handled effectively using previous schemes.
