摘　　要：针对远程证明中存在的效率问题,在现有可信计算模块(TPM)的基础上,提出了批处理方案,将短时间段内到达的请求集中进行处理,并利用Merkle树进一步减少批处理方案中通信量增长的不足.在可信移动代理服务(MAS)中的应用表明,一定时间内到达的请求越多,基于批处理的远程证明的效率提高的程度越好.Remote attestation is one of the core functionalities provided by trusted computing,which can report current platform configuration to remote challengers.Owing to the single thread access mode of TPM the terminal has to respond attestation requests in turn,which could be a performance bottleneck in trusted MAS（mobile agent server）.Remote attestation based on batching is been proposed on current TPM and can process lots of requests that arrive conncurrently within a short time concurrently.Meanwhile the increasing traffic is reduced by using Merkle hash tree.Simulations illustrate that the scheme is more effective when the number of request increases.
