摘要：
According to the broadcast encryption scheme with wide applications in the real world, a fully secure predicate-based broadcast encryption was proposed by combining with Waters dual system encryption, predicate encryption and the orthogonality property of composite-order bilinear groups. Based on the standard model, the scheme can achieve constant-size key and ciphertext, and guarantee the security of the plaintext M as well as the security of the attribute vectors. The scheme is proved by using the three static assumptions. Furthermore, the analysis results indicated that the scheme of this paper is fully secure and can satisfy the higher efficiency and practice requirement. Copyright © 2014 Binary Information Press.
