摘要:

针对当前直接匿名认证(DAA)方案设计复杂度高、计算开销大,导致制约资源受限的嵌入式或移动可信智能设备的应用的现状,提出了一种改进DAA方案. 采用双线性对密码体制,以双线性对为工具,以q强Diffie-Hellman、判定性Diffie-Hellman安全假设为基础. 分析结果表明,该方案在确保正确、安全、匿名的基础上,计算开销得到了有效降低,解决了当前资源受限可信设备的计算瓶颈问题加速推进了DAA方案在移动领域的应用.

Abstract:

Considering the current directory anonymous attestation (DAA) scheme complicated and time-consuming, which makes it limited in resource-constrained devices such as embedded, an improved DAA scheme is proposed. This scheme is based on bilinear pairing under the assumption of q strong Diffie-Hellman and decisional Diffie-Hellman. The analysis shows that this scheme is not only correct, security and anonymous, but also efficiently relieves the computation cost. This scheme further solves the computation bottleneck and accelerate application for DAA in mobile field.

Key words: trusted computing platform, directory anonymous attestation, bilinear pairing, proof of knowledge
