Abstract
In Ciphertext-Policy Attribute-Based Encryption(CP-ABE) schemes, the encryptor may set the policy in such a way that who can decrypt the encrypted message. The policy may be formed with the help of attributes. Recent CP-ABE schemes are constructed based on Linear Secret Sharing Scheme. In this paper, we use the Linear Integer Secret Sharing Scheme (LISS) for the construction. Lewko et al.[7] proposed a direction revocation method, based on that we then present a construction of CP-ABE scheme with the ability to do the direct revocation of user. The proposed construction is selectively secure under Decision Bilinear Diffe-Hellman assumption.
