摘要: 在可信计算环境中,为了弥补原有可信计算组织(TCG)提出的二进制证明方案的缺陷,提出了一种新型的基 于属性的证明((Property-Based Attestation,PISA)方案。首先介绍了基于属性的证明思想及其安全模型;然后基于改 进的I3I3+签名技术给出了一个具体的基于属性的证明构造方案,并与其他方案在性能上进行了比较;最后在随机预 言模型下证明了该方案具有配置隐私及不可伪造等安全性。

Abstract: In trusted omputing environment, to solve the problem of binary attestation scheme proposed by the trusted computing group(TCG),this paper proposed a new property-based attestation scheme. Firstly, this paper introduced the ideas of PISA and the security model of PISA-I3I3十,secondly,based on improved I3I3+ signature technology,presented a concrete construction of PISA-I3I3} scheme,and compared the scheme with other PISA schemes,finally,in oracle random model,proved the PBA-BI3} scheme meets configuration privacy and unforgcability.

Key words: Trusted computing, Property-based attestation, BB+ signature
