摘要： 目前利用单模态密码进行身份认证存在输入方式单一、安全性低等缺点。为此，提出一种异源码字可无序交融输入的方法。建立异类模态密码码字产生硬件的融合机制，给出异类模态密码码字信息归一化格式，为不同的模态信息设计不同的前置处理和密码码字分类等算法，通过异源码字公共单元实现异类模态密码码字的无序交融。基于密码键盘与黑箱子指书2类模态码字的无序交融应用实例表明，该机制可以较好地用于多模态密码输入系统。

Abstract: Single-mode password authentication has kinds of disadvantages, like single input mode and low security. This paper proposes a method to disordered fusion input for heterologic code. It builds fusion mechanism based on hardware generating of heterologic model code, gives normalized form of heterologic model code information, and designs the corresponding algorithm, like different pre-processing and classification of password code, for different model information. Disordered fusion of heterogeneous model code is implemented through public unit of heterologic code. Application of disordered fusion based on password keyboard model and black box model show that the mechanism is suitable for multi-mode password input system.

Key words: multi-mode password input system, heterologic code word, disordered fusion, password keyboard, black box keyboard
