Automatic VPN Establishment via DHCP IP Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote access and wireless local area network (WLAN) connections lack security, allowing unauthorized users to intercept data, and require cumbersome setup procedures, leading to insecure data transmission and user inconvenience.
Innovation Solution
A computerized device automatically establishes a secure connection with a wireless network by comparing received IP addresses from a DHCP server with a stored table, initiating a VPN connection if necessary, to ensure secure data transmission without user intervention, thereby preventing unauthorized access and streamlining the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional remote access and WLAN connections are used, then ease of operation is improved, but security is worsened allowing unauthorized data interception
Solution Approach 1:
The system performs preliminary security checks and establishes encryption protocols before actual data transmission begins. The client device proactively initiates authentication and key exchange procedures in advance, ensuring security measures are in place before vulnerable data communication occurs.
Solution Approach 2:
The patent introduces an intermediary security layer including authentication servers and encryption protocols that mediate between the client device and the network. This intermediary mechanism verifies credentials and establishes secure channels without requiring complex user configuration, maintaining ease of operation while enhancing security.
2Reliability
If manual VPN setup procedures are implemented, then security is improved, but device complexity and user burden increase
Solution Approach 1:
The client device is equipped with automated capabilities to perform authentication, select appropriate encryption protocols, and establish VPN connections without user intervention. The system self-configures security parameters based on network conditions and pre-stored credentials, eliminating complex manual setup while maintaining high security standards.
Solution Approach 2:
The system dynamically adjusts security parameters such as encryption strength, protocol selection, and authentication methods based on network conditions, device capabilities, and security requirements. This automated parameter optimization ensures appropriate security levels without requiring users to understand or configure complex security settings.
3Reliability
If automated secure connection establishment is implemented, then security is improved and user convenience is enhanced, but processing time and resource usage increase
Solution Approach 1:
Authentication credentials, encryption keys, and security configurations are pre-configured and cached on the client device before actual connection is needed. This preliminary preparation allows the automated secure connection process to execute rapidly when connection is required, reducing time loss while maintaining comprehensive security.
Solution Approach 2:
The system implements security protocols selectively based on network type and data sensitivity. For less sensitive communications or trusted networks, simplified authentication and encryption are applied, while more rigorous security measures are activated only when necessary. This partial application of security measures reduces processing overhead and connection establishment time while maintaining adequate protection.

Data Source
AI summary
When establishing a communications channel to a wireless network, through a wireless connection, a computerized device receives an Internet protocol (IP) address from a Dynamic Host Configuration Protocol (DHCP) server associated with the wireless network. The computerized device is configured with a table or list of IP addresses associated with wireless networks requiring a VPN or secure connection. The computerized device compares the IP address received from the DHCP server with the IP address entries of the table stored by the computerized device. If the computerized device detects a correspondence between the IP address received from the DHCP server and an IP address entry within the table, the computerized device automatically initiates a secure or VPN connection with the wireless network associated with the DHCP server. The computerized device therefore actively establishes a secure connection with the wireless network, prior to user login and without user intervention, based upon the computerized device being a client of the wireless network.
