Abstract
The encryption mechanism based on attribute regards a series of attribute sets as the user's identity, associates the ciphertext, private key with attributes and access policies, and uses Boolean expression to represent the access policy to realize fine-grained access control. When the attribute set identifies a user meets the access structure, the user can decrypt the ciphertext with his private key. This paper proposes a multi owner attribute encryption scheme of access structure. The access policies are divided into zoom-in mode and zoom-out mode. In multi owner attribute encryption, multiple owners can jointly control the control strategy of ciphertext, which is suitable for multi author scenarios. The simulation and performance analysis verify the effectiveness and efficiency of the proposed scheme in this paper.
