Abstract
Recently, ARM NEON architecture has occupied a significant share of tablet and smartphone markets due to its low cost and high performance. This paper studies efficient techniques of lattice-based cryptography on ARM processor and presents the first implementation of ring-LWE encryption on ARM NEON architecture. In particular, we propose a vectorized version of Iterative Number Theoretic Transform (NTT) for high-speed computation. We present a 32-bit variant of SAMS2 technique, original proposed in CHES’15, for fast reduction. A combination of proposed and previous optimizations results in a very efficient implementation. For 128-bit security level, our ring-LWE implementation requires only 145; 200 clock cycles for encryption and 32; 800 cycles for decryption. These result are more than 17:6 times faster than the fastest ECC implementation on ARM NEON with same security level.
