A differential cryptanalysis of the iterated block cipher based on the new round function is presented. 对基于此种新轮函数的一种迭代型分组密码进行了差分密码分析。
In cryptography,the additional characters added to a plaintext message,to ensure that its length is an integral number of blocks for encryption by a block cipher. 在密码学中，为了使明文信息的长度为分组密码加密中所用的块的整数倍，而在明文中添加的附加字符。
