摘要:

针对现有的基于属性的身份认证方案均是基于单授权中心实现的,存在密钥托管问题,即密钥生成中心知道所有用户的私钥,提出了一种基于属性的多授权中心的身份认证方案。所提方案结合分布式密钥生成技术实现用户属性私钥的(t,n)门限生成机制,可以抵抗最多来自 t-1 个授权中心的合谋攻击。利用双线性映射构造了所提方案,分析了所提方案的安全性、计算开销和通信开销,并与同类型方案做比较。最后,以多因子身份认证为例,分析了所提方案在电子凭据应用场景中的可行性。分析结果表明,所提方案具有更优的综合性能。

Abstract:

Based on the problem that the existing attribute-based identification scheme is all based on one single authority, which has a key escrow problem, that is, the key generation center knows all users’ private keys, an multi-authority attribute-based identification scheme was proposed.Distributed key generation technology was integrated to realize the (t,n) threshold generation mechanism of the user’s private key, which could resist collusion attacks from at most t-1 authorities.Utilizing bilinear mapping, a specific multi-authority attribute-based identification scheme was constructed.The security, computation cost and communication cost of the proposed scheme was analyzed, and it was compared with the same type of schemes.Finally, taking multi-factor identification as an example, the feasibility of the proposed scheme in the application scenario of electronic credentials was analyzed.The result shows that the proposed scheme has better comprehensive performance.

Key words: identification, attribute-based cryptography, multi-authority, distributed key generation
