一种采用交织的新型对称分组密码算法

A New Symmetry Block Cipher Algorithm Using Interweaving

安全密码系统是信息在发送方和接受方之间可靠传送的重要保证 ,本文提出了一种采用 2 5 6bit密钥对 2 5 6bit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 ,采用交织、移位、异或等操作增加加密系统的强度 。

Security cryptosystem is the important guarantee when information is transmitted from a sender to a receiver securely. A symmetry block cipher is introduced in this paper, the algorithm encrypts 256bit plaintext and decrypts 256bit ciphertext with 256bit key. It produces sub-keys with a primitive polynomial, uses interweaving,shift and bitwise etc. to strength the security of the cryptosystem, and is realized easily at micro-computer.
