Wi-Fi Aware DPP Provisioning for Secure Proximity-Based Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in establishing a wireless connection using the Device Provisioning Protocol (DPP) scheme due to inefficiencies in recognizing device capabilities and securely exchanging public keys before establishing a wireless connection.
Innovation Solution
The communication device sends capable information and relation information related to a public key via the Wi-Fi Aware scheme to establish a DPP connection, ensuring secure and efficient wireless connection setup by determining proximity through signal strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If public key exchange is performed after wireless connection establishment, then security is compromised, but connection setup complexity increases
Solution Approach 1:
The patent performs public key exchange and capability verification before establishing the wireless connection. The communication device sends capable information and relation information (public key) to the terminal device via Wi-Fi Aware before connection establishment, allowing security credentials to be exchanged in advance when both devices are in close proximity.
2Reliability
If capability verification is performed before connection establishment, then security is improved, but communication efficiency decreases
Solution Approach 1:
The patent performs capability verification and public key exchange before connection establishment through Wi-Fi Aware, enabling security credentials to be validated in advance. This preliminary action prevents unnecessary connection attempts with incompatible or unauthorized devices, improving overall system security.
3Productivity
If public key information is transmitted via Wi-Fi Aware, then exchange efficiency is improved, but information security risks increase
Solution Approach 1:
The patent uses Wi-Fi Aware as an intermediary channel for transmitting public key information and capability data before connection establishment. Wi-Fi Aware provides a proximity-based communication medium that allows efficient information exchange while maintaining security through the requirement of physical closeness between devices.
4Reliability
If connection establishment requires proximity determination, then security is improved, but device complexity increases
Solution Approach 1:
The patent leverages the inherent properties of Wi-Fi Aware to automatically determine proximity between devices based on signal strength measurements. The system self-verify whether devices are in close proximity without requiring additional hardware or complex verification protocols, as the Wi-Fi Aware communication itself provides the proximity indication.

AI summary
A communication device may be configured to: send capable information indicating that the communication device is capable of using a DPP scheme to a terminal device according to a Wi-Fi Aware scheme; send relation information related to a public key of the communication device conforming to the DPP scheme to the terminal device according to the Wi-Fi Aware scheme; execute a first communication with the terminal device according to the DPP scheme after the capable information and the relation information have been sent to the terminal device, the first communication including a communication of connection information from the terminal device to the communication device; and in a case where the connection information is received from the terminal device, establish a first wireless connection between the communication device and an external device via the Wi-Fi interface by using the connection information.
