提出了一种实用的灵活(或任意)长度的小域分组密码FNR加密方案。FNR表示Flexible Naor和Reingold。它可以加密小域数据格式,如IPv4,端口号,MAC地址,信用卡号码,任何随机短字符串,同时保持其输入长度。除了经典的Feistel网络之外,Naor和Reingold提出了基于伽罗瓦域GF(2 n)的成对独立置换(PwIP)函数的使用。相反,我们建议使用GF(2)中的随机N ×N可逆矩阵。
We propose a practical flexible (or arbitrary) length small domain block cipher, FNR encryption scheme. FNR denotes Flexible Naor and Reingold. It can cipher small domain data formats like IPv4, Port numbers, MAC Addresses, Credit card numbers, any random short strings while preserving their input length. In addition to the classic Feistel networks, Naor and Reingold propose usage of Pair-wise independent permutation (PwIP) functions based on Galois Field GF(2 n ). Instead we propose usage of random N ×N Invertible matrices in GF(2).
