- Abstract
Because of the large number and complex composition of cloud storage users, the data security issue has become a major constraint to the development of cloud storage. Recently, based on attribute-based encryption ( ABE) technology to solve the problem of date security in cloud storage is a hot topic while ciphertext is relatively large and complex of attribute revocation in traditional ABE schemes. This paper proposed an ABE scheme with revocation to solve the above problem and by adopting the technology of proxy re-encryption while shortening the length of ciphertext and achieving the flexible properties revocation. Besides, this scheme was under the assumption of the DBDH CPA security.
