A Lattice-based Oblivious Transfer Protocol in Malicious Model

摘要：

Utilizing Gentrys encryption scheme in Eurocrypt 10, a lattice-based 1-out-of-n obvious transfer protocol in malicious model is presented, which satisfies the privacy requirements for either sender or receiver. In our present protocol, receivers privacy is unconditional satisfied and senders privacy is guaranteed by the CPA-Security of the Gentrys Scheme which is based on the hardness of the LWE problem. Due to the fact that lattice problem is hard even on quantum computer, the proposed scheme is secure even in quantum-eve.
