摘　　要：对于加密编码算法而言,复杂性、非线性和正确性是重要的特性。而人类对知识的处理正好具备这些特性,激活扩散理论则描述了人类对知识的处理方法。受到激活扩散理论的启发,提出一种全新的基于引用图片的信息编码方法。该方法中,每个字符都用一个RGB分量的相对位置和偏移量表示,编码数据则通过激活扩散的方法生成。同一个字符可以用不同的编码表示,而相同的编码也可以表示不同的字符。通过引入激活扩散模型,该方法创建了巨大的搜索空间,从而保证了解码的复杂性;另一方面,该方法也减少了密文和明文间的相关性。Complexity, non-linearity and correctness are important features in cryptography. Human beings＇s knowledge processing just has these features. Spreading activation theory describes how human beings deal with complex and non-linear knowledge correctly. Inspired by the spreading activation theory, a new method for encoding data with references to a bitmap was advanced. In this method, a symbol was represented with a deviation range and a relative position of a contour. Encrypted data was generated by using a spreading activation process. The same symbol can be represented in different code, and the same code can represent different symbols too. This method can ensure the complexity of deciphering by implementing the spreading activation model to create a mass potential searching space. On the other hand, it can also reduce the relativity between the cipher text and the plaintext.
