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 ...

The standard aims to protect IoT device data, including RFID tags and medical implants. Four configurations focus on two main ...

Quantum computers stand a good chance of changing the face computing, and that goes double for encryption. For encryption methods that rely on the fact that brute-forcing the key takes too long wit… ...

These cryptography algorithms are designed to protect ephemeral data transmitted between edge devices and sensors, not long-term secrets.

Data is encrypted when it is generated, and symmetric encryption algorithms such as AES are used to ensure data confidentiality in transit and at rest.

All three are symmetric encryption algorithms built on a SPN—short for substitution-permutation network structure.

Public-key algorithms are important too. They help get around the fundamental drawback of symmetric-key encryption, which is that you need a secure way to share symmetric keys in the first place.

The RSA algorithm is a feast of genius that combines theoretical math and practical coding into working asymmetric cryptography. Here’s how it works.
