Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A key generating apparatus comprising: an event sensor for detecting at least one event; a key generator for generating a key set comprising at least a first key and a second key by using a key generating function, wherein the first key is generated by inputting a first value (V 1 ), which is less than a time interval (Δt) between a first event and a second event detected by the event sensor, into the key generating function, and the second key is generate…
