This paper presents a variety of plaintext-recovering attacks against SSH. We implemented a proof of concept of our attacks against OpenSSH, where we can verifiably recover 14 bi...

We initiate a study of on-line ciphers. These are ciphers that can take input plaintexts of large and varying lengths and will output the ith block of the ciphertext after having p...

We introduce “mod n cryptanalysis,” a form of partitioning attack that is effective against ciphers which rely on modular addition and bit rotations for their security. We dem...
This paper considers iterated ciphers and their resistance against linear and differential cryptanalysis. In the theory of these attacks one assumes independence of the round keys...
Abstract. In recent years, three main types of attacks have been developed against Feistel-based ciphers, such as DES[1]; these attacks are linear cryptanalysis[2], differential cr...
