8、到三天的时间内就被破译了。 NIST 计算机安全部的代理主管兼AES 选择委员会主席Edward Roback 说：“在我们拥有AES 之前，3DES 还将在今后几年提供保护。所以没有必要马上转换。AES 所提供的是一种更有效的算法。它将是一项联邦标准，但它将在IT 界广泛实施。” 据Roback 称，提议中的算法的效率是通过对信息加密和解密有多快、给出加密密钥有多快以及能对多少信息加密等几个方面进行测量的。 AES 评价委员会也要看算法占据芯片上多少空间和需要多少内存。Roback 说，选择一个更高效的AES 也会带来成本的节省和资源的更好利用。 Roback 说：“DES 是为硬件实现而设计的，而我们现在处于软件更高效的世界，我们对算法的设计有极多的了解。当我们开始大规模使用此算法，每天实现几十亿次的加密时，（算法带来的）网络开销的节省将是巨大的。”
