Abstract

Nowadays, the security of most existing PSI protocols are based on number theoretic assumptions, and with the development of quantum computing theory, these PSI protocols will become insecure. In order to solve this problem, this paper proposed a two-party PSI protocol based on ideal lattice in semi-honest model by using the decrypted features of function encryption on lattice and designing the party elements into vector forms conforming to LWE additive homomorphisms through binary decomposition. In terms of security, the PSI protocol achieves quantum-resistant security by using a function cryptographic system based on the ring learning with errors(RLWE). In terms of efficiency, the communication complexity of the proposed protocol is O(w+v) and proportional to the party elements, which ensures higher communication efficiency. And the use of ideal lattice reduces the size of the public key, which improves storage efficiency and reduces communication costs.
