This article will focus on applying AES encryption and hash authorization functions to the MQTT protocol using the popular ESP8266 chip running NodeMCU firmware.

Why should you care? AES encryption is the vault that secures onlineinformation and financial transactions by financial institutions,banks and e-commerce sites.

[Part 1 of this article begins with a review of various application security level categories and a look at hash algorithms as a basic level of security. Part 2 covers the basics for optimizing ...

Keeping the private key private only matters if integer factorization (or discrete logarithms, for the other major family of asymmetric encryption algorithms) remains a hard problem.

Rather than a novel encryption scheme, it relied on clever implementations of AES and other existing cryptographic methods to reduce the chance of introducing a fundamental flaw.

Strong symmetric ciphers, algorithms that use the same key for encryption and decryption (AES, Blowfish, etc.) will also be easier to crack with quantum computers, but only by roughly a factor of two.

Google launched Project Wycheproof on Monday, a huge set of tests for developers and software vendors to test their cryptographic software libraries.

Quantum Computation: A cryptography armageddon? ESET's Cassius Puodzius takes an in-depth look at cryptography, exploring quantum computing (one of the resources in the toolkit of cryptanalysts).
