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 ...

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 ...

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, ...

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 ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...
