Abstract:
1. A method comprising: a) loading at least one public key and private key pair in an automated banking machine that includes a cash dispenser, wherein the automated banking machine is operative to use at least one symmetric cryptography key to encrypt data with a symmetric cryptography algorithm, wherein the data is associated with at least one transaction being performed at the automated banking machine; b) enabling the automated banking machine to use at least one asymmetric cryptography algorithm with the at least one public key and private key pair; c) receiving with the automated banking machine at least one message that includes data representative of at least one second symmetric cryptography key; d) using the at least one asymmetric cryptography algorithm to decrypt and verify the at least one second symmetric cryptography key; e) receiving with the automated banking machine at least one second message that includes data representative of an encrypted at least one first symmetric cryptography key; and f) using the at least one second symmetric cryptography key to decrypt with the automated banking machine the encrypted at least one first symmetric cryptography key.
