摘要
构造了基于分组密码结构的加密认证码,并证明了它的安全性完全依赖于分组密码的安全性.对一类简易的迭代加密认证码,证明了其一阶安全性.
A class of authentication secrecy code based on the block cipher is constructed. It is proved that the security of this code is completely dependent on the security of the block cipher. Also, the one order security of a simple iterated authentication code is verified.
