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 ...

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

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

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.

Symmetric algorithms essentially depend on jumbling up the plaintext in complex ways and doing so lots of times; the key is what specifies the exact jumbling up pattern that was used.
