Ascon is a family of cryptographic primitives for authenticated encryption and hashing introduced in 2015. It selected as one the ten finalists NIST Lightweight Cryptography competition. Since its introduction, has been extensively cryptanalyzed, results these analyses can indicate good resistance this against known attacks, like differential linear cryptanalysis.Proving upper bounds probabilit...

As an indispensable part of intelligent transportation system, a traffic-sensitive navigation system can assist drivers in avoiding traffic congestion by providing services. The service provider (NSP) utilizes road condition information from nearby vehicles collected roadside units (RSUs) to guide vehicle through optimal route provided the This paper mainly focuses on tackling three key issues ...

This chapter provides a general overview of AI methods used to support the design cryptographic primitives and protocols. After giving brief introduction basic concepts underlying field cryptography, we review most researched use cases concerning techniques models primitives, focusing mainly on Boolean functions, S-boxes pseudorandom number generators. We then point out two interesting directio...

Digital currencies like Bitcoin rely on cryptographic primitives to operate. However, past experience shows that cryptographic primitives do not last forever: increased computational power and advanced cryptanalysis cause primitives to break frequently, and motivate the development of new ones. It is therefore crucial for maintaining trust in a crypto currency to anticipate such breakage. We pr...

In 2011, prompted by potential U.S. government requirements for lightweight ciphers (e.g., SCADA and logistics applications) and concerns that existing cryptographic solutions were unnecessarily restrictive, a team of cryptographic designers was formed within the Information Assurance Research Laboratory of NSA’s Research Directorate, with the goal of designing foundational lightweight cryptogr...
