Abstract

Aiming at the problems of key abuse and digital certificate management in the current lattice-based proxy re-encryption scheme, this paper proposed a new identity-based accountable proxy re-encryption scheme by introducing the accountability algorithm. This scheme used the user ID to calculate matrix as the public key and used the pre-image sampling algorithm to extract the private key, which solved the problem of digital certificate management. It used the public keys of both users to calculate and generate the re-encryption key, which improved the computational efficiency of encryption and decryption. It used the proxy's public and private keys to participate in the re-encryption calculation, completed the accountability algorithm, and inhibited the collusion of the proxy and the delegate. The security analysis shows that the scheme satisfies the chosen-plaintext attack security. In terms of efficiency, the scheme has less computational complexity and ciphertext overhead.
