摘　　要：针对目前可信计算中直接匿名认证(DAA)方案存在协议交互流程繁琐、计算量大的问题,提出了一种直接匿名认证方案IMP-DAA。以椭圆曲线上的双线性映射为理论依据,以q-SDH困难假设为安全基础,简化了协议交互流程;在保证可信计算平台安全的前提下,降低了各参与方的计算量;并从安全性和有效性两个方面进行了分析。A direct anonymous attestation scheme IMP-DAA is proposed to solve the problems,which are cumbersome protocol interaction process and large amount of calculation. The scheme is based on the theory of elliptic curve bilinear maps and the safety of q-SDH difficult assumption,and the protocol interaction process is simplified.The scheme is analyzed from the security and effectiveness,and not only remains security but also reduces the computation cost of the parties.
