METHOD AND APPARATUS FOR GENERATING NON-INTERACTIVE KEY AND METHOD FOR COMMUNICATION SECURITY USING THE SAME
First Claim
1. A key generating apparatus comprising an event detector for detecting at least one event, and a key generator for generating keys according to a result of the detecting of the at least one event detected by the event detector,wherein the key matches a key generated by a target device according to a result of the detecting of the at least one event.

Abstract
A method and apparatus for generating a non-interactive key, and a method for communication security using the same. A event is detected, and keys are generated based on the detected event. Thus, keys are generated using a small number of calculating operations with a simple interface and thus a user may easily generate the keys, and the performance of an apparatus using the keys is improved. In addition, the keys are generated without wireless interaction between nodes, thereby improving communication security.
