Abstract
A method of authenticating a payment terminal, involves the terminal generating a terminal activation request from a private encryption key and from at least one terminal credential that is uniquely associated with the terminal. The terminal activation request includes a public encryption key. The public encryption key and the private encryption key comprise an asymmetric encryption key pair. The terminal transmits the terminal activation request to a certificate server, and receives an activation response from the certificate server in response. The activation response includes a digital authentication certificate that includes the public encryption key. The terminal authenticates to a computer server, that is distinct from the certificate server, using the digital authentication certificate.
