| Abstract | This paper presents a new incremental parallelizable message authentication code (MAC) scheme adaptable to lightweight block ciphers for memory integrity verification. The highlight of the proposed scheme is to achieve both incremental update capability and sufficient security bound with lightweight block ciphers, which is a novel feature. We extend the conventional parallelizable MAC to realize the incremental update capability while keeping the original security bound. We prove that a comparable security bound can be obtained even if this change is incorporated. We also present a hardware architecture for the proposed MAC scheme with lightweight block ciphers and demonstrate the effectiveness through FPGA implementation. The evaluation results indicate that the proposed MAC hardware achieves 3.4 times improvement in the latency-area product for the tag update compared with the conventional MAC. |
