Secure data exchange with a transponder
First Claim
1. A method comprising:
- transmitting, from a base station to a transponder, a first request;
receiving, from the transponder, a first code transmitted by the transponder in response to the transponder receiving the first request from the base station;
transmitting, from the base station to the transponder, first encoded transmission information comprising a base station code encoded using the first code and a first identification;
transmitting, from the base station to the transponder, a second request;
receiving, from the transponder, a second code, the second code transmitted by the transponder in response to the transponder receiving the second request from the base station, the second code encoded by the transponder using a base station code extracted from the first encoded transmission information using the first code and the first identification;
transmitting, from the base station to the transponder, second encoded transmission information, the second encoded transmission information comprising a second identification encoded by the base station using the second code, the second identification information adapted to be extracted by the transponder from the second encoded transmission information using the second code, access to at least one memory region of the transponder provided based on a comparison of the extracted second identification information to a stored version of the second identification.

Abstract
A method includes transmitting, from a base station, a first request and receiving, from a transponder, a first code transmitted responsive to the first request. The method includes transmitting, from the base station, first encoded transmission information comprising a base station code encoded using the first code and a first identification. The base station transmits a second request, and a second code, transmitted by the transponder responsive to receiving the second request and encoded using a base station code extracted from the first encoded transmission information using the first code and the first identification, is received. Second encoded transmission information, including a second identification encoded using the second code, is transmitted from the base station. The second identification information may be extracted using the second code, access to a transponder memory region provided based on comparing the extracted second identification information to a stored version of the second identification.
