Jam Pot Cover The identity-based encryption based hidden credentials has three problems that it can not supports 1-N communication,endures no identity fuzzy and lefts open to conspiracy crack.An extended attribute encryption based hidden credentials model(EAEBHCM) was presented in to solve these three issued which making use of attribute-set certificates and decryption accuracy threshold characteristics.After analyzed the relevant research,the architecture,the system structure,the two sides trust negotiation protocol,multi-party trust negotiation protocols and how the model to solve complex logical access policies of the extended model were described in detail.

And Bed Covers the security of extended model was also analyzed.Through a typical access control scenario,the difference between old and new hidden credentials technology on the performance and security were analyzed,which clarified the advantages of the extended model.
