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 ...

Encryption is essential for protecting data, with both symmetric and asymmetric methods offering unique advantages.

This uses the SHA-3 symmetric-key algorithm, which is the latest in the Secure Hash Algorithm (SHA) family. Maxim Integrated is the first to have a SHA3-256 secure authentication device in production.

Symmetric algorithms are fast and well-understood, and the good news is that symmetric cryptography is not severely threatened by quantum algorithms.

Symmetric algorithms can be encoded and decoded with the same secret key, and that has to be shared between communication partners through a secure channel.

That’s why there is serious work underway to design new types of algorithms that are resistant to even the most powerful quantum computer we can imagine. What do these algorithms even do?

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

MIT researchers designed a computationally efficient algorithm for machine learning with symmetric data that also requires fewer data for training than conventional approaches. Their work could ...
