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 ...

Stuart Haber, a holder of patents for time-stamping technology and co-founder of Surety, is a researcher at HP Labs in Princeton, N.J., and serves as a director of the International Association for ...

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 ...

What are cryptographic hash functions? What are cryptographic hash functions? A cryptographic hash function is a mathematical algorithm that takes a data input, often referred to as a message, and ...

At the Crypto 2004 conference in Santa Barbara, Calif., this week, researchers announced several weaknesses in common hash functions. These results, while mathematically significant, aren’t cause for ...

The U.S. National Institute of Standards and Technology is having a competition for a new cryptographic hash function. This matters. The phrase "one-way hash function" might sound arcane and geeky, ...

Bitcoin offers an irreversible digital property function that prior to its invention simply did not exist. Understanding Bitcoin is a one-way hash function should make sense because a hash function ...

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, ...

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 ...
