Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...

Hashing refers to the process of using an algorithm to transform data of any size into a unique fixed sized output (e.g., combination of numbers). To put it in layman’s term, some piece of information ...

Last week, the Technology Workgroup of the Massachusetts State HIE Advisory Committee was asked to address an interesting policy and technology question. When a payload of data (a clinical summary, a ...

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...

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

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 ...
