摘要	Attribute revocation is important to the attribute-based encryption (ABE). The existing ABE schemes supporting revocation mainly focus on the revocation of the user's identity, which could only revoke the user's whole attributes by revoking the user's identity. In some cases, we wish to revoke one attribute of a user instead of the whole attributes issued to him without affecting any other user's private key, such that the user still can use his private key to decrypt as long as the unrevoked attributes of him satisfy the decryption condition. In this paper, we propose two KP-ABE schemes realizing the attribute revocation under the direct revocation model. © 2011 Springer-Verlag.; Attribute revocation is important to the attribute-based encryption (ABE).
