Title:
ELECTRONIC KEY SYSTEM AND MATCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/031607
Kind Code:
A1
Abstract:
An electronic key system is provided with a control device. The control device is provided to a communication target that is capable of communicating with an electronic key, and said control unit controls the communication target on the basis of the establishment of challenge-response authentication. The control device generates a plurality of pairs of challenge codes (C) and response codes (R) in advance and stores the result. The control device generates the response code of each pair by using an encryption key to encrypt the corresponding challenge code. The control device reads one of the plurality of pairs that are stored in advance, transmits the challenge code of the read pair, and determines that challenge-response authentication has been established when the response code that forms a pair with the read and transmitted challenge code matches the response code that is received from the electronic key.
