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.
