secret key cryptography

   Also found in: Acronyms 0.12 sec.

An encryption method that uses the same secret key to encrypt and decrypt messages. The problem with this method is transmitting the secret key to a legitimate person who needs it. Contrast with "public key cryptography," which uses a two-part key; one public and one private. See cryptography for details on both methods.
