电子商务中的加密算法研究

安全问题是电子商务得以普及与推广所面临的核心问题，而密码技术是解决安全问题的核心技术，对密码技术的加密机理及其在电子商务中的作用给以充分阐述，并对汉字文档利用MIT算法实施加密作了深入研究，众所周知，二级汉字的内部码由两个字节表示，范围在0001－7000之间，若将汉字内部码分成两段，每段只一个字节，范围降为001－256，据此可以产生实用的密钥对儿，利用这一技术，给出了可行的对汉字文档加解密算法，并用实例展示了这种算法。

Study on Encryption Arithmetic in E-commerce

Security is the key issue for E-commerce to popularize and spread, while encryption is the key technique for solving security problems. This paper thoroughly explains encryption mechanism and its function in E-commerce and deeply explores how to utilize MIT algorithm in encryption of Chinese documents. It is well known that the code of Grade Two Chinese character library ranges between 0001～7 000, with each code expressed by two types. Each type will range between 001～256,if we divided the code into two sections, with each section having only one byte. This paper also illustrates the feasible algorithm for Chinese documents encryption and decryption.
