chosen-plaintext attack meaning in Chinese

选择明文攻击

Hcbc is proven secure against chosen - plaintext attacks assuming that e is a prp secure against chosen - plaintext attacks , while hpcbc is proven secure against choen - ciphertext attacks assuming that e is a prp secure against chosen _ ciphertext attacks
但是如果假设是一个抗选择密文攻击的安全伪随机置换，则可以证明hpcbc对选择密文攻击是安全的。
Security analyses of a variant of a new block cipher system ( called cac ) based on cellular automata theory are given using two cryptanalytic approaches . the results show that this variant of cac is very insecure under chosen - plaintext attacks
利用两种方法对一个基于细胞自动机的分组密码系统cac的变形进行了分析，结果表明： cac的这种变形在选择明文攻击下是极不安全的。
