- Abstract:
- User randomization attribute privacy protection included attribute set updating leakage and attribute leakage of key in Single-CSP(Could Service Provider), which performed mainly throygh proxy authentication, zero-knowledge proof, the trusted third party and anonymous signature. Focusing on attribute protection heavily dependent on third-party key diatribution and attribute authority, this paper presented a ciphertext policy attribute-based group signcryption randomization attribute protection scheme. When a user calculated the key factor, the scheme controled CSP getting key associated attribute information by using certificateless group signcryption connectless cross-validation; it reduced the minimal number of attribute set for signcrytion need by using attribute revocation and attribute segmentation to mutual independent with sign key and encryption key, and resisted an attacker forged signatures of attribute set updating. In key service-centric, it designed the identity verifying mechanism of group signcrypyion, and controls masquerading as other user. The scheme implemented the protection of the randomization attribute security and message privacy.
