We first prove the truthfulness of a conjecture on the nonlinearity of monotone Boolean functions in even dimension, proposed in the recent paper “Cryptographic properties of mo...
Recent observations on polynomial structures of AES-like round functions are analysed in this note. We present computational evidence that input/output bits of AESlike 2-round tra...
The block cipher Simon has a very simple round function. This simplicity allows us to compute the correlation matrix of the round function. Despite its simplicity, Simon exhibits s...
The Russian Federation’s standardization agency has recently published a hash function called Streebog and a 128-bit block cipher called Kuznyechik. Both of these algorithms use ...
There are many kinds of attacks that can be mounted on block ciphers: differential attacks, impossible differential attacks, truncated differential attacks, boomerang attacks. W...
We introduce a new technique for tight security proofs called work factor partitioning. Using this technique in a modified version of the framework of D¨ottling and Schr¨oder (C...
—Modular multiplication is the fundamental and compute-intense operation in many Public-Key crypto-systems. This paper presents two modular multipliers with their efficient arch...
In universal composability frameworks, adversaries (or environments) and protocols/ideal functionalities often have to exchange meta-information on the network interface, such as a...
