Learn more about hash functions, including how they protect data integrity and secure blockchain transactions in ...

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 ...

Hybrid hash function post-quantum cryptography research: a new paper on IACR ePrint formalizes a construction whose collision resistance simultaneously requires breaking both the elliptic-curve ...

Hash functions are cryptography’s most widely used primitives, in that they are a fundamental building block used for a wide variety of constructions. The recent attacks of Joux, Wang, and others ...

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 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) ...

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 ...

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 ...
