Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses. Symmetric algorithms convert plain-text data ...

In the last section we discussed the potential for optimizing algorithms, which can be done, but sometimes may not result in the type of performance required. As was mentioned, you can always move the ...

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 ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

The FIDO2 industry standard adopted five years ago provides the most secure known way to log in to websites because it doesn’t rely on passwords and has the most secure form of built-in two-factor ...

Thirteen, 53 and 433. That's the size of quantum computers in terms of quantum bits, or qubits, which has significantly grown in the last years due to important public and private investments and ...

As technological advancements surge forward, the specter of quantum computing looms ever larger. While the promise of quantum computers holds the potential to revolutionize fields like weather ...

When analyzing the security of PoS (Point of Sale) applications, we have to take into account the necessary involvement of magnetic stripes and cardholder data, which is extremely sensitive ...
