摘要

In the driven of big data, social computing and information security is undergoing rapid development and beginning to cross. This paper describes a key-policy attribute-based signcryption scheme which has less computation costs than existing similar schemes by utilizing secure outsourcing of scientific computation in cloud computing and eliminates overhead for users, the ciphertext is short, compact, the correctness of transformation algorithm is verifiable. The decrease of ciphertext is 17 %. Additionally, new scheme remits the key escrow problem and is proven selective security in the standard model, it could be verified publicly, applied in mobile devices.
