Security of a modern block cipher is commonly measured in terms of its resistance to known attacks. While the provable security approach to block ciphers dates back to the first C...
In this paper, we present a statistical saturation attack that combines previously introduced cryptanalysis techniques against block ciphers. As the name suggests, the attack is st...
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...
In this paper, we present an enhanced cryptanalysis of the Substitution Cipher Chaining mode (SCC) [1]. In [2], SCC-128 (SCC which uses AES with 128-bit key) was broken using 5 att...
We propose a general framework for differential and linear cryptanalysis of block ciphers when the block is not a bitstring. We prove piling-up lemmas for the generalized different...
