Wireless Access Point Dynamic Access Rule Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In public wireless environments, managing access between devices securely is challenging due to security risks from random clients connecting to the same network, making it difficult to allow communication while preventing hacking and ensuring efficient access control.
Innovation Solution
Implementing a system where a wireless access point requests and applies access rules from a remote server to control IP and MAC address access, allowing or denying network packets based on dynamically updated rules, and enabling automatic device discovery while filtering communication to ensure secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clients are allowed to communicate freely over a LAN in public wireless environments, then network accessibility and device discovery are improved, but security risks increase due to potential hacking and unauthorized access
Solution Approach 1:
The patent introduces an access point as an intermediary device that mediates all communication between wireless clients. The access point intercepts, inspects, and controls network packets, allowing it to enforce access policies and prevent direct peer-to-peer communication that would expose clients to security risks while maintaining the ability to allow legitimate communication through the intermediary
2Object-affected harmful factors
If access control restrictions are implemented to prevent hacking, then security is improved, but network flexibility and ease of reconfiguration deteriorate due to manual configuration requirements
Solution Approach 1:
The patent implements dynamic access control where the access point can modify access policies in real-time based on current network conditions, client identities, and security requirements. The system transitions from static manual configuration to dynamic automated policy enforcement, allowing the network to adapt flexibly to changing circumstances while maintaining security
Solution Approach 2:
The access point monitors network traffic and client behavior, using this feedback to automatically adjust access control decisions. The system continuously evaluates packet content, client credentials, and network state to dynamically enforce appropriate access policies without requiring manual reconfiguration
3Manufacturing precision
If manual reconfiguration is used to enable client communication, then access control precision is improved, but operational complexity and difficulty of implementation increase
Solution Approach 1:
The access point performs self-service by automatically authenticating clients, inspecting packets, and enforcing access policies without requiring manual administrator intervention. The system autonomously manages access control precision through automated credential verification, packet filtering, and policy enforcement mechanisms

AI summary
A first set of access rules is received from an access configuration service. The first set of access rules specifies addresses of devices authorized for a first user. A second set of access rules is received from the access configuration service. The second set of the access rules specifies addresses of devices authorized for a second user. At a wireless access point, a network packet associated with the first user is received. The first set of access rules is applied to filter the network packet.
