视觉密码在交互式身份认证中的应用研究

摘要

Based on a comprehensive analysis about attackforms challenge-response authentication scheme faced , this paper applied the visual cryptographic techniques to interactive authentication scheme.This scheme takes advantage of the pseudo daracteristics to ensure the authentication session is notreused,and doesn'tuse complex traditional encryption algorithm,so as to improve the convenience and security of the identity program.%分析“挑战-响应”式身份认证方案面临的攻击形式，将视觉密码技术应用到交互式的认证方案中，利用视觉密码具有的伪随机数的特性，保证身份认证会话不被重用，并且不使用复杂的传统密码算法，提高了身份认证方案的便捷性和安全性。最后，对身份认证方案进行了常见攻击的抵抗分析。
