一种新的对称分组密码算法的设计

Design of a new type of password algorithm with symmetrical grouping

提出了一种采用256bit密钥对256bit明文进行加解密的对称分组密码算法,它利用本原多项式产生子密钥,采用移位、异或等操作增加加密系统的强度,并能在单片机上很方便地实现。

A symmetry block cipher is introduced in this paper,the algorithm encrypts256bit plaintext and decrypts256bit ciphertext with256bit key.It produces sub-keys with a primitive polynomial,using shift and bit-wise etc.to increase the security of the cryptography,and is realized easily at micro-computer.
