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 ...

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 ...

Cryptography aficionados, say hello to a new hash algorithm backed by the National Institute for Standards and Technology (NIST). Dubbed Keccak (pronounced "catch-ack"), the secure hash algorithm, ...

The DeepCover Secure Authenticator (DS28E22) combines crypto-strong, bidirectional, secure challenge-and-response authentication functionality with an implementation based on the FIPS 180-3-specified ...

Cryptocurrency has undeniably transformed the financial landscape, with Bitcoin and Litecoin emerging as trailblazers in the realm of decentralized digital currencies. At the heart of these blockchain ...

This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. This ...

The DS28E25 combines secure challenge-and-response authentication functionality based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256) with 4Kb of user-programmable EEPROM. Additional ...

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 ...

Bringing to a close a five-year selection process, the U.S. National Institute of Standards and Technology (NIST) has selected the successor to the encryption algorithm that is used today to secure ...
