In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

The National Institute of Standards & Technology (NIST) is set to announce the winning hash algorithm that ultimately will become the next-generation industry standard, SHA-3. But security expert ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...
