Three Snakes in One Hole: A 67 Gbps Flexible Hardware for SOSEMANUK with Optional Serpent and SNOW 2.0 Modes
With increasing usage of hardware accelerators in modern heterogeneous Systemon-Chips (SoCs), the distinction between hardware and software is no longer rigid. The domain of cryptography is no exception and efficient hardware design of so-called software ciphers are becoming increasingly popular. In this paper, for the first time we propose an efficient hardware accelerator design for SOSEMANUK...
متن کاملA Dynamic FPGA Implementation of the Serpent Block Cipher
A JBits implementation of the Serpent block cipher in a Xilinx FPGA is described. JBits provides a Java-based Application Programming Interface (API) for the run-time modification of the configuration bitstream. This allows dynamic circuit specialization based on a specific key and mode (encrypt or decrypt). Subkeys are computed in software and treated as constants in the Serpent datapath. The ...
متن کاملOn Algebraic Relations of Serpent S-Boxes
Serpent is a 128-bit block cipher designed by Ross Anderson, Eli Biham and Lars Knudsen as a candidate for the Advanced Encryption Standard (AES). It was a finalist in the AES competition. The winner, Rijndael, got 86 votes at the last AES conference while Serpent got 59 votes [1]. The designers of Serpent claim that Serpent is more secure than Rijndael.In this paper we have observed that the n...
متن کاملNothing better than a Python to write a Serpent
Serpent is a 128-bit block cipher designed by Ross Anderson, Eli Biham and Lars Knudsen as a candidate for the Advanced Encryption Standard, a competition sponsored by the National Institute of Standards and Technology to define a successor to DES. Serpent is designed to be faster than DES and more secure than triple-DES. It is in the public domain and there are no restrictions on its use: the ...
متن کاملA Differential-Linear Attack on 12-Round Serpent
Serpent is an SP Network block cipher submitted to the AES competition and chosen as one of its five finalists. The security of Serpent is widely acknowledged, especially as the best known attack so far is a differential-linear attack on only 11 rounds out of the 32 rounds of the cipher. In this paper we introduce a more accurate analysis of the differentiallinear attack on 11-round Serpent. Th...
