Explore the fundamentals of permutation-based cryptography in this 19-minute conference talk from FSE 2025, chaired by Yaobin Shen. Delve into the theoretical foundations and practical applications of cryptographic systems built around permutation functions, examining their security properties and implementation considerations. Learn about the latest research developments in this specialized area of cryptography, including design principles, security analysis methods, and real-world applications. Gain insights into how permutation-based approaches differ from traditional cryptographic constructions and understand their advantages in modern cryptographic protocols. This presentation serves as the opening talk in a three-part series on permutation-based cryptography, providing essential background knowledge for understanding advanced topics in symmetric cryptography and hash function design.
