Receiver-based trusted multicast non-repudiation service:MNORS
Minmin Liu · Computer Engineering and Applications Journal · 2007
Propose the multicast NRR service:MNORS based on the mobile agent security scheme:MABCM.Under the protection of mobile agent blackbox,through the method of embedded decryption key,the trusted NRR evidence can be forcibly generated in the untrusted computing environment of receivers by the NRR mobile agent.So we have solved the technique problem of generating trusted NRR evidence in untrusted receivers’ environment.In the research subject of receiver-based Multicast Non-Repudiation,there existed few results and the only result,due to the authors’ knowledge,is Nark,whose implementation must be based on smart card.And the security of its method of generating pseudo-random sequence has not been strictly analyzed and proved.Compared with Nark,MNORS have the following advantages:pure software implementation,high-level transparency,high-level security and scalability.
