Explore the fundamentals of differential cryptanalysis in this 21-minute conference talk from FSE 2025, chaired by Virginie Lallemand and presented by TheIACR. Delve into this powerful cryptanalytic technique that analyzes how differences in input affect the resultant difference at the output of a cryptographic function. Learn about the mathematical foundations, practical applications, and methodologies used in differential cryptanalysis to evaluate the security of block ciphers and other cryptographic primitives. This presentation serves as the first part of a two-talk series on differential cryptanalysis, providing essential knowledge for cryptographers, security researchers, and anyone interested in understanding modern cryptanalytic methods used to assess cipher strength and vulnerability.
