Novel conspiracy attack immune generalized interactive authentication scheme for virtual enterprises with traceability
Dake He · Computer Integrated Manufacturing Systems · 2010
There were several preliminary interactive authentication schemes for Virtual Enterprise (VE), but none of them could resist conspiracy attacks or trace the members' identities which participated in a Virtual Certificate Authority (VCA) signature's generation. To solve these problems, a novel conspiracy attack immune generalized interactive authentication scheme for VE with traceability was proposed. In this new scheme, the conspiracy attack immune property was obtained by introducing signers' inherent secret keys' and public keys' information into VCA signature, and the traceability was realized by constructing identity tracking database and y-value's revocation list. Furthermore, the new scheme could locate errors by partial signature's verification function. Analysis shows that the new scheme was more secure and was suitable for various VE's organization forms. It provided a feasible solution for VE's interactive authentication.
