A Delay-Efficient Ring-LWE Cryptography Architecture for Biometric Security

This paper presents an efficient scheme and architecture based on ring-LWE cryptography for biometric data security. The proposed architecture significantly reduces the number of polynomial multipliers compared to the traditional ECC cryptosystems. As a result, the encryption and decryption time for a single ring-LWE operation can be reduced up to 49.7% and 19.6% compared to the existing works, respectively. The simulation results show that the proposed architecture outperforms conventional ECC architectures in terms of computation complexity and processing time.
