Document Type and Number:
WIPO Patent Application WO/2024/090461
Kind Code:
A1
Abstract:
This key system includes: a first information processing device included in an electronic lock device; and a second information processing device that is included in an electronic key device for operating the electronic lock device and is communicably connected to the first information processing device. After a communication connection is established between the first information processing device and the second information processing device, the first information processing device acquires combined data in which at least first data and second data different from the first data have been combined. The first information processing device transmits the combined data to the second information processing device. The first information processing device calculates a first hash value that satisfies a prescribed condition on the basis of a first nonce value and the combined data. The second information processing device calculates a second hash value that satisfies the prescribed condition on the basis of a second nonce value and the combined data. The first information processing device determines whether the first hash value and the second hash value match.
