Title:
AUTHENTICATION PROCESSING DEVICE, AUTHENTICATION PROCESSING SYSTEM, AUTHENTICATION PROCESSING METHOD AND AUTHENTICATION PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/108993
Kind Code:
A1
Abstract:
A communication device (300) transmits a processing request (301), including request information, a digital signature, and an electronic certificate, to a control device (200). The control device (200) transmits a verification request (201) including the electronic certificate to a verification server (400). The verification server (400) verifies the electronic certificate included in the verification request (201), and transmits authentication-use reference information, including the verification result, as a verification response (202) to the control device (200). If the verification result included in the authentication-use reference information indicates validity, the control device (200), using the request information and a public key included in the electronic certificate, verifies whether or not the digital signature is valid. If the digital signature is valid, the control device (200) executes the requested processing in accordance with the request information, and transmits a processing response (302) to the communication device (300).
