Automatic IPsec Connection via Domain Name Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securely connecting to a remote server lack indication of security protocols other than HTTPS and require user-initiated VPN setups, making it difficult to enforce security policies and protect sensitive information.
Innovation Solution
A method and apparatus that determine support for IP layer security protocols by analyzing domain names, performing key exchanges, and connecting using shared secrets, leveraging protocols like IPsec and DNSsec to establish secure connections automatically without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP layer security protocols are used to securely connect to remote servers, then security policy enforcement is improved, but user operation complexity increases due to requiring client software initiation
Solution Approach 1:
The system automatically determines whether to establish IPsec connections based on domain name resolution results without requiring user initiation or configuration. The client autonomously performs security protocol selection and connection establishment, eliminating the need for users to manually configure VPN client software while maintaining strong security policy enforcement.
Solution Approach 2:
Security protocol support is determined during the domain name resolution phase, before the actual connection is established. This preliminary determination of IPsec compatibility allows the system to automatically prepare and initiate appropriate security measures, preventing security policy violations before they occur rather than requiring user intervention.
2Reliability
If manual VPN client software initiation is required, then security control is improved, but automation level decreases
Solution Approach 1:
The client system automatically performs security protocol determination and connection establishment based on domain name resolution results. The system self-manages the entire security negotiation process including determining IPsec support, performing key exchange protocols, and establishing encrypted connections without requiring user initiation or manual VPN client software configuration.
Solution Approach 2:
Security protocol compatibility is determined during the preliminary domain name resolution phase, allowing the system to automatically initiate appropriate security measures before connection establishment. This preliminary security assessment enables fully automated connection handling while maintaining strict security control.
3Reliability
If security protocols are enforced at the IP layer, then data protection is improved, but compatibility requirements increase
Solution Approach 1:
The system dynamically changes security protocol parameters based on server capabilities determined during domain name resolution. By detecting whether the remote server supports IPsec and adjusting the security protocol accordingly, the system maintains strong data protection for compatible servers while automatically falling back to standard TCP/IP connections for incompatible servers, thus achieving both high security and broad compatibility.
Solution Approach 2:
The security protocol selection is dynamic rather than static, adapting to the capabilities of the remote server. The system determines IPsec support during connection setup and adjusts security measures in real-time, allowing it to enforce strong IP layer security when possible while maintaining compatibility with servers that do not support advanced security protocols.

AI summary
A method for securely connecting to a remote server that provides improved Internet security. In the method, a client receives a request to connect to a remote server associated with a domain name. The client, when resolving the domain name, determines whether the remote server supports at least one predetermined IP layer security protocol. The client performs a key exchange protocol with the remote server to generate at least one shared secret in response to determining that the remote server supports the at least one predetermined IP layer security protocol. The client connects to the remote server using the at least one shared secret in the IP layer security protocol.
