A computer-based apparatus comprising:

• means for generating a first key and a random number;
• means for sending the first key and the random number to a server over a first network, wherein the first network provides a first communication path between the computer-based apparatus and the server;
• means for encrypting the random number and an identifier associated with the computer-based device to create first encrypted information, wherein the random number and the identifier are encrypted using the first key;
• means for sending the first encrypted information to the server via a second network, wherein the second network provides a second communication path between the computer-based apparatus and the server;
• means for receiving second encrypted information from the server over one of the first network or the second network, wherein the second encrypted information includes the random number, the identifier, and a second key;
• means for decrypting the second encrypted information using the first key;
• and
• means for storing the second key.

A method performed by a computer-based server, the method comprising:

• receiving, from a device, a first key and a first random number over a first network, wherein the first network provides a first communication path between the device and the computer-based server;
• receiving first encrypted information over a second network, wherein the second network provides a second communication path between the device and the computer-based server, and wherein the first encrypted information includes a second random number and an identifier associated with the device;
• decrypting the first encrypted information using the first key;
• comparing the first random number to the second random number;
• if the first random number is the same as the second random number, generating a second key;
• and
• sending a data package to the device, wherein the data package includes the first random number, the identifier, and the second key, and further wherein at least a portion of the data package is encrypted using the first key.

A computer-based server apparatus comprising:

• means for receiving a first key and a first random number over a first network from a device, wherein the first network provides a first communication path between the device and the computer-based server apparatus;
• means for receiving first encrypted information from the device over a second network, wherein the second network provides a second communication path between the device and the computer-based server apparatus, and wherein the first encrypted information includes a second random number and an identifier associated with the device;
• means for decrypting the first encrypted information using the first key;
• means for comparing the first random number to the second random number;
• means for generating a second key and associating the second key with the identifier if the first random number is the same as the second random number;
• means for generating a data package, wherein the data package includes the first random number, the identifier, and the second key, wherein at least a portion of the data package is encrypted using the first key;
• and
• means for sending the data package to the device via one of the first network or the second network.
