基于NTRU新型认证密钥协商协议的设计
New design of authenticated key agreement protocol based on NTRU
摘要
Abstract
NTRU is the most practical cryptosystem based on the lattice structure currently.However,comparing with the encryption and signature schemes based on the NTRU,there was very few papers in concern of the key agreement protocol.To address these problems,this paper proposed a new authenticated key agreement protocol,which was based on the NTRU lattice.Under the random oracle model,the proposed scheme is provably secure in the eCK model,also can resist man-in-themiddle attack,replay attack,impersonation attack and achieves weak perfect forward secrecy.Compared with the traditional DH and ECDH scheme,the scheme not only has higher computational efficiency,but also resists quantum attacks because of the shortest vector problem on lattice.关键词
