Characteristic automated search of cryptographic algorithms for distinguishing attacks (CASCADA)

Automated search methods based on Satisfiability Modulo Theory (SMT) problems are being widely used to evaluate the security of block ciphers against distinguishing attacks. While these provide a systematic and generic methodology, most their software implementations limited small set attacks, extending requires significant effort expertise. In this work, authors present cryptographic algorithms for attacks (CASCADA), an open-source Python library primitives, specially ciphers, with bit-vector SMT solvers. The tool CASCADA implements property framework herein proposed several SMT-based automated differential, related-key rotational-XOR, impossible-differential, impossible-rotational-XOR, linear zero-correlation cryptanalysis. is result huge engineering effort, it provides many functionalities, modular design, extensive documentation complete suite tests.
