The National Institute of Standards and Technology (NIST) today announced the winner of its five-year competition to select a new cryptographic hash algorithm, one of the fundamental tools of modern ...

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.

Security experts vying to have their technology selected as the next cryptographic-hash algorithm standard for the U.S. government need to submit their entries this week. Then they will have a long ...

The National Institute of Standards and Technology (NIST) has opened a competition to develop a new cryptographic “hash” algorithm, a tool that converts a file, message or block of data to a short ...

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 ...

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 ...
