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.

The public-key algorithm is used for distributing the key and the symmetric-key algorithm handles the bulk of the communications encryption. The astute reader may have noticed that the public-key ...

ASC X9 has released a new standard, X9.24-3, that allows the use of the AES DUKPT algorithm to enhance security in retail financial transactions.

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 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?

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 ...
