Abstract: The Cryptographic Trace proposed by G.Vigna is a representative method protecting mobile agent from write attack. This thesis gives an improved method, to offset the inadequacies of this method. This method makes the check immediately and initiatively.At the same time, the large storage of trace and the messages required are reduced. And what's more, the exact difference between the compared states can be obtained, which is not available in cryptographic trace.
