Abstract: The current identity-based encryption based hidden credential can not support 1-N communication, endures no identity fuzzy and lefts open to conspiracy crack, which brings great limitation to its availability. In this paper, an attributcbased encryption based hidden credentials extended model was presented which solves those dilemmas of basic hidden credential system, meanwhile, the extended model keeps the advantages in protecting all the certificates, resources and strategics safe in trust negotiation. Since in AI3E system, each participant has and only has one attributcset certificate, the extended model significantly improves the efficiency of decryption process. On the other hand, through the random control in certificate issue process, the possibility of conspiracy crack is also eliminated. In addition, we described their performance, security and applications in detail. Finally, the farther research directions were suggested.
