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 ...

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 ...

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, ...

Three cryptographers at Stanford University recently came up with a clever solution to the persistent problem of identity theft on the Internet. Wily hackers in Russia, China, and other countries send ...

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 ...

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 ...

The vulnerability in the SHA-1 one-way hash function, which recently rocked the cryptographic world, is not seen as a threat to a new generation of one-time password products based on the encryption ...

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 ...
