Device, method, and medium for facility management verification

摘要

An equipment manager manages the operating state of equipment. A user verification processor performs user verification according to a request from a monitoring terminal, and when user verification is successful, generates for each facility management device a verification code in which verification data, to which a digital signature has been added using a self-owned secret key, has been encoded using a public key of each facility management device, and transmits the verification codes to the monitoring terminal. After receiving the verification code, a verification code analyzer decodes the verification code using the self-owned secret key, and performs verification by verifying the digital signature using the public key of a representative facility management device. When verification is successful, a Web server is able to monitor and manipulate data that indicates the operating states of all of the equipment that is managed by the equipment manager.

主权项

1. A facility management device being a representative facility management device among a plurality of facility management devices that manages equipment, comprising:
a user verifier, embodied as a computer with a central processing unit (CPU) and a memory, that performs a user verification according to a request from a monitoring terminal; a verification code generator, embodied as the computer, that generates verification codes for each of the plurality of facility management devices by encoding verification data using unique public keys of each of the plurality of facility management devices, when the user verification is successful, and to transmit those verification codes to the monitoring terminal; and a public key list storage that stores a list of public keys of each of the plurality of facility management devices, wherein the verification code generator:
adds a digital signature that uses a self-owned secret key to the verification data as data that indicates the user verification was successful, andgenerates verification codes for each of the facility management devices as data that was encoded using data to which a digital signature was added as the public keys of each of the facility management devices stored in the public key list storage.
