AES中SubBytes算法在FPGA的实现

SubBytes algorithm of AES in the FPGA implementation

介绍了AES中,SubBytes算法在FPGA的具体实现。构造SubBytes的S-Box转换表可以直接查找ROM表来实现。通过分析SubBytes算法得到一种可行性硬件逻辑电路,从而实现SubBytes变换的功能。

This article describes the SubBytes algorithm of AES in FPGA implementation. Build SubBytes of S-Box transform table is directly through ROM table to achieve. By analyzing the SubBytes algorithm, the article find a kind of hardware logic circuits which can achieve SubBytes transform function.
