You might not have realized it, but the next great battle of cryptography began this month. It's not a political battle over export laws or key escrow or NSA eavesdropping, but an academic battle over ...

As the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) prepares to announce the winner of its competition to find the next-generation cryptographic hash algorithm, ...

Developers of two open source code libraries for Secure Shell—the protocol millions of computers use to create encrypted connections to each other—are retiring the SHA-1 hashing algorithm, four months ...

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 ...

If you want to find out if two spam emails are identical without comparing every single byte in them – which would take an undue amount of time – you digest the file into a short string, known as a ...

After nine years of research and competitions, the National Institute of Standards and Technology released the final version of its Secure Hash Algorithm-3 standard Wednesday. SHA-3 is a cryptographic ...

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 ...

Hash functions are cryptography’s most widely used primitives, in that they are a fundamental building block used for a wide variety of constructions. The recent attacks of Joux, Wang, and others ...

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

Researchers unveiled the first-ever practical collision attack the cryptographic hash function SHA-1. Researchers unveiled on Thursday the first practical collision attack for the 22-year old ...
