摘要

本文在通用可组合模型下构造了一个基于格的模糊密码认证密钥交换协议。通过已知的密码认证密钥交换方案，引入随机模糊等式协议和遗忘传输协议，将密码认证密钥交换改进为模糊密码认证密钥交换。首先，双方经过两轮的遗忘传输协议，然后根据交换的信息进行密钥交换。模糊密码认证密钥交换满足即使用户之间的密码存在噪声，密钥交换仍然是可能的。因此，相对于密码认证密钥交换，模糊密码认证密钥交换适用于更多的应用场景，并且构建了通用的组合安全。

Fuzzy Password Authentication Key Exchange protocol in universal composable framework for blockchain privacy protection

In this paper, we construct a lattice-based fuzzy Password Authentication Key Exchange protocol in universal composable model. Through the known Password Authentication Key Exchange scheme, the Randomized Fuzzy Equality protocol and the Oblivious Transfer protocol are introduced to improve Password Authentication Key Exchange into fuzzy Password Authentication Key Exchange. First, the parties go through two rounds of Oblivious Transfer protocol, and then the key exchange is achieved based on the information exchanged. fuzzy Password Authentication Key Exchange satisfies that even if there is noise in the passwords between users, key exchange is still possible. Therefore, fuzzy Password Authentication Key Exchange is suitable for more application scenarios compared to Password Authentication Key Exchange, and the construction is universal composable security.

期刊介绍： The quality of software, well-defined interfaces (hardware and software), the process of digitalisation, and accepted standards in these fields are essential for building and exploiting complex computing, communication, multimedia and measuring systems. Standards can simplify the design and construction of individual hardware and software components and help to ensure satisfactory interworking. Computer Standards & Interfaces is an international journal dealing specifically with these topics. The journal • Provides information about activities and progress on the definition of computer standards, software quality, interfaces and methods, at national, European and international levels • Publishes critical comments on standards and standards activities • Disseminates user''s experiences and case studies in the application and exploitation of established or emerging standards, interfaces and methods • Offers a forum for discussion on actual projects, standards, interfaces and methods by recognised experts • Stimulates relevant research by providing a specialised refereed medium.
