Hashing and Encryption, do you know what these are? Some might have heard the names before and believe they are the same. But that is not the case at all. You see, much of the data that is moving ...

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 ...

COMMENTARY--I can imagine a world where the computers needed no security. Where there were no passwords, no security checks, and no firewalls. Where the computers communicated freely and shared ...

Cryptography can mean either the analysis or the deciphering of codes, ciphers and cryptograms. Also known as: cryptanalysis, cryptanalytics, cryptology. First Seen1900 B.C. Cryptography is a method ...

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 ...

Compare SHA-256 vs Keccak-256 cryptographic hash functions, security, performance, and blockchain applications.

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 ...
