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 ...

Members can download this article in PDF format. The security of cryptographic applications critically relies on symmetric keys and private keys that are continually kept secret. The method used to ...

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 ...

Field Programmable Gate Arrays (FPGAs) have emerged as a versatile platform for implementing cryptographic algorithms, offering a balance between flexibility, performance and energy efficiency. Recent ...

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 ...

The path to a secure future in a world with quantum computers just became a bit clearer. This week, the U.S. National Institute of Standards and Technology (NIST) announced the algorithms that were ...
