Title:
AUTHENTICATION/AUTHORIZATION SYSTEM, DEVICE, AUTHENTICATION/AUTHORIZATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/091183
Kind Code:
A1
Abstract:
An authentication/authorization system according to an embodiment of the present invention includes: a plurality of devices that perform mutual authentications according to an authentication protocol using ID-based cryptography and that perform authorizations; and an authentication/authorization platform that generates IDs and a secret key to be used for the mutual authentications and authorizations. The authentication/authorization system is characterized in that: the authentication/authorization platform comprises an ID generating unit that generates IDs including at least the identifiers of the devices and device-related information, a generation unit that generates the secret key of the devices from the IDs, and a distribution unit that distributes the IDs and the secret key to the devices corresponding to the identifiers included in the IDs; and the devices each comprise a mutual authentication unit that uses the ID of the device itself and the secret key to perform a mutual authentication with another device, a determination unit that, upon the performance of the mutual authentication with the other device, uses device-related information included in the ID of the device itself and device-related information included in the ID of the other device to determine whether a predetermined authorization requirement is satisfied or not, and an authorization unit that authorizes a request from the other device to the device itself when it is determined that the authorization requirement is satisfied.
