| Summary: | 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 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. |
