The National Institute of Standards and Technology today announced a public competition to pick a new cryptographic hash algorithm that would become the new federal information processing standard.

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 ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

Cryptographic hash functions secure data by providing a unique fixed-length output for each input. These functions are essential in blockchain for data integrity and secure transactions. Understanding ...

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 ...

Three years ago, Ars declared the SHA1 cryptographic hash algorithm officially dead after researchers performed the world’s first known instance of a fatal exploit known as a “collision” on it. On ...

The National Institute of Standards and Technology retired one of the first widely used cryptographic algorithms, citing vulnerabilities that make further use inadvisable, Thursday. NIST recommended ...
