1. decryption
   The process of recovering an encrypted message using a decryption key and a known algorithm to make it readable again - the reverse of the encryption process. In private key systems, the same key is used for encryption and decryption. In public key systems the encryption and decryption keys are different. Both are used in mobile networks; examples from the GSM world include the A3, A5 and A8 algorithms. Encryption/decryption is related to authentication and the whole area is dealt with as AAA (Authentication, Authorisation and Accounting) in the Internet world.
