This chapter excerpted from Hardware Implementation of Finite-Field Arithmetic, gives an example of finite-field application—namely, the implementation of the scalar product (point multiplication) ...

Before we move into the meat of this article, let’s define a couple terms related to cryptography. The syllable crypt may make you think of tombs, but it comes from a Greek word that means “hidden” or ...

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 ...

Modern cryptography is embedded in countless digital systems and components. It's an essential tool for keeping data secure and private. Yet one of the biggest limitations with cryptography, including ...

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 ...

Once quantum computers become a commercial reality, they will change the ground rules for cryptography. Here's how quantum cryptography would work, and an explanation of the benefits and pitfalls of ...

Cryptographers want encryption schemes that are impossible for tomorrow’s quantum computers to crack. There’s only one catch: they might not exist. When we check email, log in to our bank accounts, or ...

A fundamental concept in the technology sector, Moore’s law foretells the exponential rise in computing power over time and is named after Gordon Moore. Gordon Moore, the co-founder and emeritus ...

Cryptography: Napoleon's Bad Example | RealClearScienceFor all his military genius, the one idea that Napoleon could not quite seem to grasp was the importance of cryptography. Most prominently, this ...
