Why does Adversary not construct correspondence between plain texts and secret texts, and store the correspondence, since RSA function is a permutation over domain.(see Oded Goldreich, Foundation of Cryptograph P56) Alice can encipher, Adversary can do it also. He need not to decipher, he only need to compare a secret text in his storage and pick out relative plain text. This attack is easy, so RSA is fragile if it confronts powerful enemy(NSA) whose storage is marvellous. 11/11/2003.
