There were several preliminary interactive authentication schemes for virtual enterprise(VE),but none of them could realize multi-policy authentication,and some couldn't resist conspiracy attacks,some couldn't trace the members' identities,some easily formed safety bottleneck and efficiency bottleneck as it put the leader on the dominant position.To solve these problems,this paper proposed a multi-policy novel conspiracy attack immune interactive authentication scheme for VE with traceability.The new scheme realized multi-policy authentications by using different threshold value t,obtained the conspiracy attack immune property by introducing signers' inherent public keys and secret keys,and realized the traceability by constructing identity tracking database and effective identity tracking protocol,meanwhile the new scheme could verify the correctness of partial signatures.Analysis shows that the new scheme is more secure as its multi-policy authentication,resisting conspiracy attack,traceability,partial signatures verifiability,so it is suitable for more application fields.
