基于文本的密码认证方案往往更容易受到诸如肩部冲浪或隐藏摄像头等攻击。为了克服传统方法的漏洞,可视化或图形化密码方案已经被开发出来,作为基于文本的密码方案的可能替代方案。由于单纯采用图形密码认证也存在一些缺点,因此开发了图形和文本相结合的密码认证方案。提出了一种基于形状和文本的混合密码认证方案。网格中使用笔画的形状作为原始密码,用户可以通过传统的输入设备使用文本密码登录。这种方法对肩部冲浪或隐藏摄像头有很强的抵抗力。该方案具有较高的可扩展性和灵活性,提高了认证过程的安全性。并对该方法的安全级别进行了分析。
Text-based password authentication scheme tends to be more vulnerable to attacks such as shoulder surfing or a hidden camera. To overcome the vulnerabilities of traditional methods, visual or graphical password schemes have been developed as possible alternative solutions to text-based password schemes. Since it also has some drawbacks to simply adopt graphical password authentication, schemes using graphic and text have been developed. In this paper, a hybrid password authentication scheme based on shapes and texts is proposed. Shapes of strokes are used in the grid as the original passwords and users can log in with textual passwords via traditional input device. The method provides strong resistance to shoulder surfing or a hidden camera。Moreover, the scheme has high scalability and flexibility to enhance the authentication process security. The analysis of the security level of this approach is also discussed.
