Cryptographic algorithms lie at the heart of modern information security, and substitution box (S‐box) design is a critical component in achieving robust encryption. S‐boxes provide the nonlinearity ...

In the world of information security, we often see statements such as ‘secured by 128-bit AES’ or ‘protected by 2048 bit authentication’. We are used to people asking about the strength of the ...

In July, the National Institute of Standards and Technologies selected four cryptography algorithms as national standards for public key security in order to prepare for an era of quantum computers, ...

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 ...

Following a public comment period and review, the National Institute of Standards and Technology (NIST) has removed a cryptographic algorithm from its draft guidance on random number generators.

Snowden documents say NSA introduced weaknesses to the number-generating guidance. The National Institute of Standards and Technology has finally removed a cryptographic algorithm from its draft ...
