Patent ID: 8467532

Claim:
A method of authenticating a wireless communication device, comprising the steps of: transmitting to a communication device a first message from a server; generating a first random number at the server; generating a first encrypted signal at the server using a second message and the first random number; transmitting the first encrypted signal from the server to the communication device; decrypting the first encrypted signal at the communication device; retrieving the first random number at the communication device; generating at least two new random numbers at the communication device; generating a second signal at the communication device using the two new random numbers and the first random number; encrypting the second signal at the communication device; transmitting the second signal from the communication device to the server; decrypting the second signal at the server using a Deterministic Random Sequence Generation (DSRG) process; validating the second signal using a hash value comparison at the server; generating a response based on the hash value comparison at the server; and transmitting the response to the communication device by the server.
