Cloud WPA3 Provisioning for Secure IoT Wi-Fi Onboarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks are vulnerable to attacks such as eavesdropping and data theft, and devices without user interfaces, like IoT devices, face challenges in securely authenticating and connecting to wireless networks using traditional security protocols like WPA2 and WPA, which rely on pre-shared keys (PSKs) that can be vulnerable to brute-force attacks.
Innovation Solution
Implementing WPA3-based authentication protocols with Device Provisioning Protocol (DPP) and secure public key infrastructure (PKI) for wireless devices, enabling secure credential exchange without manual configuration, and associating unique user identifiers with WPA3 pre-shared keys to authenticate and provision network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WPA2 and WPA protocols with pre-shared keys are used for wireless network authentication, then network security is improved through encryption and authentication mechanisms, but vulnerability to brute-force attacks increases and device complexity increases due to manual configuration requirements
Solution Approach 1:
The patent changes the authentication parameters from traditional PSK-based systems to WPA3-SAE (Simultaneous Authentication of Equals) which uses a different mathematical approach with per-packet encryption keys derived from a master password, making brute-force attacks computationally infeasible while maintaining user-friendly authentication
Solution Approach 2:
The patent introduces a cloud-based provisioning system as an intermediary that automatically manages authentication credentials and device registration. This mediator handles the complex authentication processes and provides automated credential distribution, reducing the burden on individual devices while enhancing security through centralized management
2Reliability
If traditional WPA2 authentication with manual configuration is used, then network security is maintained, but ease of operation deteriorates for devices without user interfaces and device complexity increases
Solution Approach 1:
The patent implements self-service authentication where IoT devices automatically perform authentication with the network without requiring manual user intervention. The device autonomously generates credentials, communicates with the provisioning system, and configures network settings automatically, enabling seamless onboarding for devices without user interfaces
Solution Approach 2:
The patent performs preliminary actions by pre-configuring authentication parameters and credentials in the cloud-based provisioning system before devices need to connect. The system pre-establishes authentication contexts and automatically provisions devices upon their first connection, eliminating the need for manual configuration at the time of device onboarding
3Ease of operation
If cloud-based provisioning with automated authentication is implemented, then ease of operation is improved for device onboarding, but device complexity increases due to additional authentication protocols
Solution Approach 1:
The patent uses a cloud-based provisioning system as an intermediary that handles the complexity of WPA3-SAE authentication, key derivation, and credential management. The cloud system absorbs the computational and protocol complexity, presenting simplified authentication interfaces to both users and devices while maintaining robust security mechanisms in the background

AI summary
Systems, methods, and non-transitory, machine-readable media may facilitate wireless network provisioning. In one example, a method for provisioning wireless network access to a wireless device includes: creating, in a cloud-based provisioning system, a wireless network access profile that includes a user identifier associated with the wireless device, receiving, on an access point, an authentication request sent from the wireless device, identifying, by the cloud-based provisioning system, the wireless device based on the user identifier associated with the wireless device, performing, on the cloud-based provisioning system, WPA3-based authentication to authenticate the wireless device, and providing, by the access point, network access to the wireless device.
