摘要:

大数据技术的快速发展和广泛应用,给传统的身份认证技术带来了新的安全挑战,因此研究适应于复杂网络环境的安全身份认证技术具有重要的实际意义。在基于传统生物特征的认证技术的基础上,文章提出了一个基于同态加密与生物特征的身份认证方案。该方案借助基于RLWE的同态加密技术和一种消息编码技术,将用户的生物特征信息加密后外包存储,用户的身份信息匹配过程在加密域进行。方案在数据传输过程中引入随机数,用于抵抗重放攻击。文章利用大数据环境下的多种典型的攻击手段对方案进行安全性分析证明,结果表明方案对复杂网络环境具有良好的适用性。

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
