Wu for CAESAR competition. First we describe slid properties of keys and IVs for the cipher. For each (Key, IV) pair, the probability that there is another pair which generates an identical state up to a...
we analyse the security of COFFE. Our attack shows that even under the assumption that the primitive hash function is ideal, a valid ciphertext can be forged with 2 enquiries with success
SAT based cryptanalysis is one of efficient ways to investigate about desire properties of symmetric ciphers. In this paper we show our research and new experimental results in the case of SAT based, direct cryptanalysis of DES-like ciphers. For this, ha
The Vigenere cipher applies different Caesar ciphers to consecutive letters. If the key is 'PUB', the first letter is enciphered with a Caesar cipher with key 16 (P is the 16th letter of the alphabet), the second letter with another, and the third letter with another. When we get to ...

The library provides general purpose analysis tools, as well as premade modules to break well known ciphers. fromlantern.modulesimportshiftfromlanternimportfitnessciphertext="iodj{EuxwhIrufhLvEhvwIrufh...
Originally published in the New Mathematical Library almost half a century ago, this charming book explains how to solve cryptograms based on elementary mathematical principles, starting with the Caesar cipher and building up to progressively more sophisticated substitution methods. Todd Feil has updated...
MORUS is an authenticated cipher submitted to the ongoing CAESAR competition and becomes one of 15 candidates entering the third round. This paper studies the bit-based division property and differential trails of MORUS-640/1280 with Mixed Integer Linear Programming (MILP) tool. The key-recovery at...
of the round functions that are instantiated by PRFs. TWINE, which is a GFS-based block cipher, was proposed by Suzakiet al.[18] after a comprehensive study done by Suzaki and Minematsu [17] showing the effect of the choice of sub-block permutation on the diffusion, the number of ...
