Electronic information key system
First Claim
1. An electronic information key system comprising at least one electronic information key and a locking device unlocked with the electronic information key,wherein the electronic information key including:
- an ID code storage having a plurality of memory areas, each storing different ID codes;
a body, resin-treated, for installing the ID code storage; and
a contact, mounted on the body and electrically connected to the ID code storage, and wherein the locking device including;
a key holder for electrically contacting the contact of the electronic information key;
a registered ID code storage for storing values corresponding to the ID codes stored in any one of the plurality of memory areas of the ID code storage of the electronic information key; and
a controller for comparing the ID codes stored in an area of the ID code storage with the ID codes stored in the registered ID code storage to thereby verify whether the electronic information key is duly operating, when the contract electrically contacts the key holder, wherein the controller authenticates the ID codes read from the electronic information key, generates new ID codes by using the ID codes and a certain variable, and, subsequently, the new ID codes are stored as updated ID codes in the electronic information key and stored as the registered ID codes in the locking device, and wherein the variable is generated based on the time duration that the electronic information key contacts the locking device.
