Abstract
A client device is registered with a network server by having the network server generate a key number and emit an optical representation of the key number for optical reception by the client device. The client device determines the key number from the received optical representation, and encrypts or decrypts a communication using the key number, or a value based on the key number. In one embodiment, the optical representation may be either an infrared signal or visible light signal.
Claims17
A method for registering a client device with a network server comprising:
- generating a key number by the network server;
- emitting an optical representation of the key number;
- receiving said optical representation by the client device;
- determining, by the client device, the key number from the optical representation;
- and
- encrypting a communication using a value based on the key number.

A system comprising:
- a network;
- a network server coupled to the network, wherein the network server is to,
- generate a key number,
- emit an optical representation of the key number, and
- encrypt a communication using a value based on the key number;
- and
- a client device coupled to the network, wherein the client device is to,
- receive said optical representation,
- determine the key number from the optical representation, and
- decrypt the communication using the value based on the key number.
