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

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 ...

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.

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

Communication channels are often secured using cryptographic algorithms. Broadly speaking, cryptographic algorithms can be classified as symmetric and asymmetric. With symmetric key algorithms, the ...

For the last half century the principal encryption method was symmetric key, i.e., the use of the same algorithm to encrypt and decrypt by using the same key at the encryptor and decryptor.

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.
