Third-Party Mediator for Secure Wi-Fi Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for authenticating access to Wi-Fi smart devices through mobile phone Apps are insecure as users manually enter passwords, allowing illegal users to easily acquire and use access passwords.
Innovation Solution
A method and system that involves a first device acquiring the device identification of a second device bound with a user account, sending this information to a third-party device, which then sends an access password for authorization, ensuring secure access by verifying the password matches the generated access password.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually enter access passwords on mobile phone Apps to access Wi-Fi smart devices, then the ease of operation is improved, but the security deteriorates as illegal users can easily acquire and use access passwords
Solution Approach 1:
The patent introduces a third-party device as an intermediary that generates and manages access passwords. Instead of users manually entering passwords, the third-party device automatically generates passwords and sends them to both the user's mobile phone and the Wi-Fi smart device. This mediator approach eliminates manual password entry while maintaining security, as the third-party device controls password distribution and can revoke access by generating new passwords.
Solution Approach 2:
The patent replaces the mechanical system of manual password entry with an automated electronic system. The third-party device uses software algorithms to automatically generate access passwords and transmit them electronically to the user's mobile phone and the target device. This substitution eliminates the vulnerability of manual password entry while maintaining ease of operation through automated processes.
2Reliability
If a third-party device generates and manages access passwords automatically, then the security is improved, but the device complexity increases
Solution Approach 1:
The third-party device is designed to perform multiple functions: generating access passwords, transmitting passwords to users, transmitting device identifiers to smart devices, and revoking access by generating new passwords. By consolidating these security-related functions into a single multi-functional device, the system avoids the need for multiple separate components, thereby reducing overall system complexity while maintaining high security.
Solution Approach 2:
The third-party device autonomously generates access passwords using cryptographic algorithms and manages the authentication process without requiring manual intervention. The device automatically transmits passwords to authorized users and can independently revoke access by generating new passwords. This self-service capability reduces the need for complex manual management procedures and simplifies the system operation.

AI summary
The present disclosure relates to a method, apparatus and system for authenticating access of a first device with a first user account to a second device with a device identification bound with a second user account. The method includes acquiring, by the first device, the device identification of the second device to by accessed. Subsequently, the method includes sending the device identification and the first user account to a third-party device. The third-party device receives the device identification and the first user account, sends an authentication request to a login terminal for the second user account when the first user account is different from the second account, receives a permission access response for an access authorization front the login terminal, and sends an access password associated to the first device. Then, the method includes receiving the access password, and accessing the second device using the access password.
