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 ...

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...

BLAKE3 is the most recent evolution of the BLAKE cryptographic hash function. Created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and Zooko Wilcox-O'Hearn, BLAKE3 combines general purpose ...

In the previous blog post, “Securing Offload Engines for a Robust Secure SoC System,” we briefly looked at some of the methods employed for achieving embedded security, i.e., cryptography, hardware ...

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 ...

After nine years of research and competitions, the National Institute of Standards and Technology released the final version of its Secure Hash Algorithm-3 standard Wednesday. SHA-3 is a cryptographic ...

Over the past several months, we've seen major breaches exposing numerous usernames and passwords. The eBay and Adobe breaches impacted millions of accounts. Snapchat was compromised. With every ...

I’m going to talk about the security behind Bitcoin addresses and keys, called Public Key Cryptography. This includes SHA256, Random Number Generators(RNGs), Hash Functions, and Elliptic Curve Digital ...

Attackers are recording, and sometimes forging, vast volumes of human communication. Some of this communication is protected by cryptographic systems such as the Rivest–Shamir–Adleman (RSA) system and ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...
