  1. (, International Conference on Security and Privacy in Communication Systems SecureComm)
    Public-key cryptography based on the lattice problem is efficient and believed to be secure in a post-quantum era. In this paper, we introduce carefully-optimized implementations of Kyber encryption schemes for 64-bit ARM Cortex-A processors. Our research contribution includes optimizations for Number Theoretic Transform (NTT), noise sampling, and AES accelerator based symmetric function implementations. The proposed Kyber512 implementation on ARM64 improved previous works by 1.79×, 1.96×, and 2.44× for key generation, encapsulation, and decapsulation, respectively. Moreover, by using AES accelerator in the proposed Kyber512-90s implementation, it is improved by 8.57×, 6.94×, and 8.26× for key generation, encapsulation, and decapsulation, respectively.
