Fuzzy Identity Based Encryption Scheme with Some Assigned Attributes

摘要：

In this paper the concept of Fuzzy IBE schemes with some fixed attributes (SAA-FIBE) is proposed and one construction of it is presented. SAA-FIBE scheme can be viewed as a variant of SW scheme described in 1 which demanding no fixed positive or negative attributes. In our scheme, a user with identity ωcan decrypt the message that is encrypted with a set of attributes,ωif and only if |ω∩ω|≥d and ω must have or must have not some attributes described in encryption policy. The scheme are both error-tolerant and secure against collusion attacks in the SPID-FIBE attack model.
