I'm not exactly sure in which direction I have to think. I believe decryption will also be linear since in linear algebra the inverse of a linear function is also linear. The fact that the attacker can choose 128 ciphertexts hints at ...

WebJun 28, 2012 · Hi Daniel. Thank you for your answer. There is still one more related (sub)question to clear this all up. Cipher "EXP-EDH-DSS-DES-CBC-SHA" needs probably DSS params to be set up to be used but we are not able to find appropriate function inside M2Crypto/OpenSSL to do it (like set_tmp_rsa() and/or set_tmp_dh() are used in other … WebThe two-square cipher is a polygraphic substitution cipher. The original plaintext is divided into groups of a few letters. Then, each group is replaced by another previously determined group of characters. The two-square cipher operates on groups of the size of two letters. Before encryption one should prepare two tables, using words (or ...
