RLWE-based ciphertext-policy attribute proxy re-encryption
To solve LWE-based proxy re-encryption schemes cannot achieve fine-grained access and low efficiency problem,a ciphertext-policy attribute-based proxy re-encryption scheme was proposed.The scheme based on linear secret sharing scheme,RLWE and attribute encryption could shorten the key size,reduce th...

| description | To solve LWE-based proxy re-encryption schemes cannot achieve fine-grained access and low efficiency problem,a ciphertext-policy attribute-based proxy re-encryption scheme was proposed.The scheme based on linear secret sharing scheme,RLWE and attribute encryption could shorten the key size,reduce the ciphertext space and improve the efficiency of encryption and decryption.At the same time,the linear secret sharing matrix was used as an access matrix to meet the requirements of authorized person fine-grained commissioning control and to resist the collusion between the agent and the authorized person.In addition,the proposed scheme is shown to be secure under the ring learning with errors assumption in the standard model. |
