Peripheral Device Authentication via Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth peripheral devices lack authentication processes, allowing non-genuine or unsafe devices to connect to information processing devices, compromising safety and security.
Innovation Solution
A system that includes a peripheral device capable of performing encrypted communication with an authentication server, where the device transmits identification and signature information for authentication, and only allows communication after verifying authenticity, with periodic re-authentication and valid period management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication process is implemented for peripheral devices, then safety and security are improved, but device complexity and communication overhead increase
Solution Approach 1:
The patent performs authentication in advance before allowing peripheral device connection. The authentication server verifies the peripheral device's identity and generates authentication information (including digital signatures) beforehand, so that when connection is requested, the verification is already complete, ensuring safety without adding complexity to the connection process itself
Solution Approach 2:
The patent introduces an authentication server as an intermediary between the information processing device and peripheral device. This mediator handles the complex authentication processes, digital signature verification, and security management, so that the peripheral device and information processing device themselves don't need to implement complex authentication logic, thus improving safety while minimizing added complexity
2Reliability
If authentication process is implemented for peripheral devices, then safety and security are improved, but communication time and process duration increase
Solution Approach 1:
The authentication process is executed in advance before actual communication begins. The authentication server verifies the peripheral device and generates authentication information beforehand, so that when the information processing device requests connection, the verification is already complete, minimizing the time loss during actual communication operations
Solution Approach 2:
Once authentication is completed and authentication information is generated, it can be reused for subsequent communication sessions. The patent allows the information processing device to connect using previously verified authentication information, eliminating the need to repeat the full authentication process for each connection, thus maintaining continuous useful communication without repeated time losses

AI summary
This first communication section transmits, to an authentication server, an encryption key, identification information capable of uniquely identifying a peripheral device, and signature information of the identification information. A second communication section receives data based on an authentication process performed in the authentication server on the basis of the identification information and the signature information transmitted by the first communication section, then, encrypts second data transmission request information, and transmits the encrypted request information to the authentication server. A third communication section receives second data which is encrypted and transmitted from the authentication server in response to the request information transmitted by the second communication section, then decrypts the second data, and transmits the decrypted second data to the authentication server. A communication process execution section receives third data based on a result indicating that authenticity of the second data transmitted by the third communication section has been confirmed in the authentication server, and then, performs encrypted communication with the predetermined communication device.
