Using SAT Solvers to Finding Short Cycles in Cryptographic Algorithms [PDF]
International Journal of Electronics and Telecommunications, 2020 A desirable property of iterated cryptographic algorithms, such as stream ciphers or pseudo-random generators, is the lack of short cycles. Many of the previously mentioned algorithms are based on the use of linear feedback shift registers (LFSR) and ...

Experimental FIA Methodology Using Clock and Control Signal Modifications under Power Supply and Temperature Variations [PDF]
Sensors, 2021 The security of cryptocircuits is determined not only for their mathematical formulation, but for their physical implementation. The so-called fault injection attacks, where an attacker inserts faults during the operation of the cipher to obtain a ...
