Asymmetric-key algorithms use a combination of private and public keys while symmetric algorithms use only private ones, commonly referred to as secret keys.

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.

The result of this requirement is a much larger key size than symmetric-key algorithms for an equivalent amount of security. As an example, 512-bit RSA is considered to be about the same level of ...

While Shor's algorithm could be used to target asymmetric key cryptography, Grover's could impact symmetric key cryptography.

As noted by Daniel J. Bernstein, the creation of quantum computers that can effectively execute Grover’s algorithm would necessitate at least the doubling of today’s symmetric key lengths.

With the increasing number of high-profile data and privacy breaches in the Internet of Things (IoT) systems, businesses and consumers have a greater awareness of the need for security when buying ...

Once quantum computers become a commercial reality, they will change the ground rules for cryptography. Here's how quantum cryptography would work, and an explanation of the benefits and pitfalls of ...
