Hybrid hash function post-quantum cryptography research: a new paper on IACR ePrint formalizes a construction whose collision ...

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 ...

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 ...

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 ...

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 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 ...

Bitcoin quantum computing threat is real: experts say slow governance, not its cryptography, makes Bitcoin uniquely ...

Galaxy pledged up to $5 million in grants for developers working on Bitcoin’s quantum security and elected a council of ...

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 ...
