常見例句As the application of orthomorphic permutations in cryptography, we simply emphasize the advantage provided by such permutation in increasing the security of a block cipher. 簡要強調(diào)了利用正形置換強化分組密碼的優(yōu)點;利用正形置換設(shè)計了一種密碼安全布爾函數(shù)。We develop a necessary and sufficient condition under which an orthomorphic permutation is linear, and also improve the method available of constructing nonlinear orthomorphic permutations. 給出了一類線性正形置換的計數(shù)方法;對現(xiàn)有的非線性正形置換的構(gòu)造方法進行了改進;lambert orthomorphic conical projection 蘭勃特等角圓錐投影transverse cylindrical orthomorphic chart 橫軸墨卡托投影地圖orthomorphic map projection transformation 正形變換orthomorphic permutation polynomial 正形置換多項式 返回 orthomorphic
