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 ...

Imagine taking a block of data and turning it into a unique string of characters. Like giving it a digital nickname that never changes (unless the data does!). That’s a hash. Whether the original data ...

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

Cryptographic hash functions are crucial in ensuring the security and integrity of information across diverse industries. They protect sensitive financial transactions in banking, verify data ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

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 ...

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 ...
