文章摘要
为了设计一种基于格困难问题的强安全认证密钥交换协议,分析了DXL12和DXL14方案中缺少认证功能导致容易遭受中间人攻击等缺陷,提出一种基于Binary-LWE的认证密钥交换协议。该协议具有两轮消息交互,不依赖于数字签名提供隐式密钥认证,并采用2012年Micciancio和Peikert在欧密会上提出的陷门函数来提供双方认证功能。在随机语言机模型下将安全性直接建立在Binary-LWE问题的困难性假设上,具有前向安全性、抗中间人攻击、抗冒充攻击等安全属性。由于该方案的安全性是基于格上困难问题,所以可以抵抗量子攻击。
Abstract
The purpose of this paper is to design a strong secure authenticated key exchange protocol based on lattice problem. Because of the lack of authentication function in DXL12 and DXL14 schemes, it is easy to suffer from man-in-the-middle attacks. Therefore, we propose an authentication key exchange protocol based on Binary-LWE. There is a 2-round message exchange in the protocol that is independent on the implicit authentication from digital signature, and the protocol supply the authentication by the trapdoor function which proposed by Micciancio and Peikert on EUROCRYPT 2012.Under the random oracle model, the security of this protocol is based on the hard assumption on Binary-LWE problem. The protocol can resist man-in-the-middle attack, impersonation attack and also has the forward secrecy. Finally the proposed protocol can resist quantum attacks because of the hard assumption on lattice problem.
