ACIM-QMM: Efficient Analog Computing-in-Memory Accelerator for QC-MDPC McEliece Cryptosystem
SessionOf Circuits and Secrets: Emerging Hardware Security Primitives and Cryptographic Accelerators
DescriptionQuasi-cyclic moderate density parity-check McEliece (QMM) cryptosystem is designed to mitigate the security threat posed by quantum computers, and is considered to be a promising candidate for post-quantum cryptography (PQC). However, the growing requirement of data encryption bring severe challenge for QMM implementation in terms of latency and hardware overhead. In this work, we firstly propose ACIM-QMM, an analog computing-in-memory (CIM) accelerator design for QMM cryptosystem. The empowerment of analog circuits and CIM make the design efficiently generating key and ciphertext encrypting while breaking the performance bottleneck of PQC constrained by digital computing paradigm. In the experiment, ACIM-QMM can work in low relative error, and it can achieve 31.4×~288.1× speedup compared with SOTA hardware of QMM cryptosystem. Furthermore, the results also demonstrate that ACIM-QMM can achieve maximum 3.12× area and 20.32× energy efficiency improvement comparing with other PQC hardware for 256-bit security.
