Wireless device for verifying identification
First Claim
1. A wireless device for responding to an external identification request comprising:
- a first memory means for storing a password having a plurality of bits;
a second memory means for storing a mask having a plurality of bits;
a comparison means for comparing the bits of said mask with the bits of said password;
a processing means for producing a response to said external identification request, said response having a plurality of bits such that each bit of the response is binary one, when the corresponding bit of said mask and of said password is binary one.

Abstract
A wireless communication device using a verification protocol for verifying the identification of the wireless device by a wireless network control station in the presence of eavesdroppers is disclosed. Upon receiving a call request from a wireless device claiming a particular identity, the wireless network control station sends a mask consisting of binary digits in a random order. The wireless device is expected to respond to this mask with a reply that is consistent with both the password contained in the device and the mask. Specifically, the bits of both the password and the mask are "ANDed" and the result transmitted to the wireless network control station as the reply.
