Finally , by studying the key schedule of rijndael that is easy to uncover the seed keys , i put forward a new way to solute it . this new algorithm takes the snowslide and the relation of them into accout . more , an ameliorate of the key arrangement is discussed . and executed by ansi c implement 这种算法也兼顾了密钥的雪崩效应和它们之间的关系，并考虑了能量分析对它的攻击，另外，还对密钥的编排进行了改进，使得种子密钥进行了二次加密，密文更加安全，并在c语言环境中实现。
