M2 cipher's
WebThe M1, M2 and M3 are also known by their designator: Ch.11g . As an example: the cipher wheels have letters (A-Z) around the rim, rather than numbers (01-26) and the machine has a 4V or 6V socket, so that it could be powered from a …

Web13 oct. 2015 · If an attacker uses a chosen-cipher-text attack, how can they decrypt any plaintext by choosing 128 ciphertexts? 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 ... Web14 ian. 2014 · 2 Answers Sorted by: 12 If the two encrypted messages are using the same stream cipher and the same key, C1 xor C2 results in M1 xor M2 where C1 and C2 are the respective ciphertext and M1 and M2 are the corresponding plaintext. You can then recover the plaintext using a technique known as crib dragging.
