摘要：

At Eurocrypt 1998, Blaze, Bleumer and Strauss [8] presented a new primitive called Proxy Re-Encryption (PRE). PRE is a public key encryption which allows a semi trusted proxy to alter a ciphertext for Alice (delegator) into a ciphertext for Bob (delegatee) without knowing the message. To the best of our knowledge there does not exist any lattice based identity based unidirection PRE scheme. In this paper, we have costructed lattice based identity based unidirection PRE scheme. Our scheme is noninteractive. In this scheme, we have used Micciancio and Peikert's strong trapdoor [16] for lattices which is simple, efficient and easy to implement than [3].
