摘　　要：可信计算中最核心的就是TPM。由于TPM硬件的工作模式是单进程,服务提供商对远程证明的请求只能依次进行响应,当有大量远程证明请求达到时,必然会出现响应效率问题,进而会成为系统运行的瓶颈。针对当前分布式系统中远程证明中存在的这个问题,提出了一种基于椭圆曲线数字签名算法的代理多签名远程证明方式,利用代理的方式,服务提供商可对计算机集群集中进行远程证明,进而提高远程证明的效率,同时可满足可信平台系统的安全性和隐私性。TPM is the most core of the trusted computing. Owing to the model of TPM hardware is a single process, service pro- vider can only respond the request of the remote attestation in turn. When a large number of requests of remote attestation reach at the same time, issues of response efficiency arose which will become the bottleneck of the system. In the view of this problem of remote attestation in distributed system, a new proxy multi-signature remote attestation based on the elliptic curve digital sig- nature algorithm is proposed. To use this proxy mode, the remote attestation is processed centralized by service provider. Mean- while, the efficiency of the remote attestation is improved and the security and privacy of trusted platform is satisfied.
