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.

Ron Rivest developed the RC2 algorithm in the late 1980s as a replacement for DES. RC2 encrypts data in 64-bit blocks and has a variable key size of 8 to 128 bits in 8-bit increments. Lotus ...

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 ...

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

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.

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.

Asymmetric algorithms use different keys — one public, one private — to validate two parties’ identities and then to securely establish the shared secret (symmetric) key between them.

It’s a symmetric key algorithm, so there’s one flaw with it. It’s not just the government, either: militaries, banks, and corporations across the world trust AES-256 to keep their data secure ...

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.
