基于RLWE认证密钥协商算法的设计

Design of Authenticated Key Agreement Algorithm Based on RLWE

密钥协商算法允许参与者在非安全信道中交换信息共同协商会话密钥用于保密通信,是密码学中最关键技术之一。本文基于RLWE困难问题,利用四舍五入密钥共识算法,Filtering引理及哈希函数,设计了一个新的基于RLWE困难问题的认证密钥协商算法。新的认证密钥协商算法具有高效与可证明安全的特点。

Key agreement algorithm allows participants to exchange information in the open channel to gener-ate a secure temporary session key to ensure secret communication, which is one of the key tech-nologies in cryptography. In this paper, a novel authenticated key agreement algorithm based on RLWE difficulty problem is proposed using rounded key consensus algorithm, filtering lemma and hash function. The new authenticated key agreement algorithm is proved to be efficient and prova-bly secure.
