Protecting Mobile Agent´s Computation Results with Reversible Watermarking and Digital Signature

Mobile agent technology is considered as a potential replacement of traditional client server model for implementing future internet applications. However this cannot be achieved without addressing security issues associated with the Mobile Agent Systems. In this paper we present a framework for protecting mobile agent´s computation results against malicious host. Our proposed framework uses reversible watermarking for content recovery and cryptographic technique like digital signature providing stronger protection against malicious host. Our experimental results suggest that the framework can be implemented in e-commerce application efficiently.
