Abstract:

The rapid development and wide application of big data technology have brought new security challenges to the traditional identity authentication technologies. Therefore, it is of great practical significance to develop secure identity authentication technologies adapting to complex network environment. On the basis of authentication technologies based on traditional biometric, this paper presents an identity authentication scheme based on homomorphic encryption and biometric. The scheme utilizes the homomorphic encryption technology based on RLWE and a message encoding technology to encrypt the users' biometric information and outsource them for storage. The matching process of the user's identity information is performed in the encrypted domain. Random numbers are adopted during the data transmission process to resist replay attacks. This paper uses a variety of typical attack methods in big data environment to prove the security of the scheme. The results show that the scheme has good applicability to complex network environment.

Key words: big data technology, identity authentication, biometric authentication, homomorphic encryption
