摘要
为解决传统单因子认证造成的数据泄露和身份冒充等问题,针对文化资源可信共享提出基于区块链的多因子身份认证方案。考虑多种身份因素,利用区块链分布式账本的不可篡改性和分布性构造异构数字身份模型。通过非对称加密算法和异或运算,实现异构数字身份的可信复用和多元主体的快速认证。安全分析和仿真结果表明,所提方案在安全性和效率方面优于已有的多因子认证方案,能有效降低身份认证成本。
To solve the problems of data leakage and identity impersonation caused by traditional single factor authentication,a multi-factor identity authentication scheme based on blockchain was proposed for the trusted sharing of cultural resources.Considering a variety of identity factors,a heterogeneous digital identity model was constructed using the tamper resistance and distribution of the blockchain distributed ledger.Through asymmetric encryption algorithm and exclusive OR(XOR)operation,the trusted reuse of heterogeneous digital identity and fast authentication of multi-agent access were realized.Security analysis and simulation results show that the proposed scheme outperforms existing multi-factor authentication schemes in terms of security and efficiency,and can effectively reduce the cost of identity authentication.
