| 总结: | Identity-based Identification (IBI) schemes permit the user to participate in the intercommunication with a verifier to prove himself to gain resources. It is the cryptographic primitive without relying on certificates. Nevertheless, IBI shcemes only support single user interaction with the verifier. Under certain situations, such as group booking or a committee authentication, it may be inappropriate. A new security model is proposed in this work to examine the notion and model multiply identification schemes in detail without certificates; consolidating techniques from hierarchical, cluster structures and providing a collection of users to produce their secrect keys in varying manners with diverging security properties. |
