摘要
首先研究了Twofish算法的结构,然后针对128位的密钥长度,用Altera公司的FPGA器件实现了该算法的加密、解密和密钥变换。通过与Rijndael实现结果的比较,说明Twofish的硬件实现灵活、占用资源少。
In this paper,a version of the Twofish with 128-bit key length has implemented using Altera FPGAs,All the features of the algorithm have implemented,including sub-key generation,encryption and decryption.Upon comparison with Rijndael,the results show the Twofish is a very flexible design and use less hardware resources.
