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, ...

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 ...

The PKI industry recommends that every SHA-1 enabled PKI move to the vastly more secure SHA-2. Here's why and how. For the past two years, I’ve been busy helping Public Key Infrastructure (PKI) ...

Cryptographic hash functions are a key building block in embedded security. They take input data of any size and convert it into a fixed-length value, called a hash or message digest. This hash acts ...

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 ...
