对Rijndael算法中密钥扩展的优化

The optimization of key expansion in Rijndanel method

为了推进Rijndael数据加密工程中密钥扩展工作,文中用GF(28)域知识和C#知识,设计了具体实现密钥扩展的代码,是实现密钥扩展的新方法,并经过上机实验证明可行,还具有稳定可靠、高效率和高速度的特点。

In order to promote the Rijndael data encryption key expansion project work,this paper design a concrete realization of the key expansion of the code withGF（28） and C # knowledge.This code is to achieve the key expansion of the new method.In the end this codes not only proved to be feasible in the experiments,but also with stable,reliable,efficient and high speed characteristics.
