1. A computer implemented method for authenticating a relay with a service provide system using an encrypted key file, comprising:

  • generating the encrypted key file wherein generating comprises the steps of;

    receiving an identifier associated with the relay;

    generating a registration key data set;

    recording the registration key data set in a database;

    encrypting the registration key data set forming an encrypted registration key data set; and

    making the encrypted registration key data set available to the relay as the encrypted key file;

    transmitting the encrypted key file from the relay to the service provider system when the relay is instantiated;

    transmitting the identifier that identifies the relay with the encrypted key file;

    decrypting the encrypted key file received at the service provider system to derive a first random number and a second random number;

    searching the database to determine whether there is an unbound key data set matching the first random number, the second random number, and the identifier associated with the relay;

    responsive to determining that the database fails to include the unbound key data set matching the first random number, the second random number, and the identifier associated with the relay, terminating authentication of the relay with the service provider; and

    responsive to determining that the database includes the unbound key data set matching the first random number, the second random number, and the identifier associated with the relay, searching the database to determine whether there is a bound key data set matching the first random number, the second random number, and the identifier associated with a relay, wherein when the bound key data set match is present in the database, authenticating the relay with the service provider system.
