Virtualization Layer for Cross-Platform IPsec Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Internet Protocol Security (IPsec) protocols face limitations in cross-platform compatibility, operating system dependencies, and inflexibility, leading to inadequate data encryption and security in hybrid environments, especially over the Internet, and lack effective solutions for authentication, authorization, and accounting in modern data communications.
Innovation Solution
A virtualization layer is introduced on user devices that allows for adaptable encryption and operation on packets without modifying the operating system, enabling cross-platform security, advanced authentication and authorization schemes, and consumer-side accounting, while isolating the network from the operating system and providing proactive network defense.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IPsec protocols are used for data encryption, then communications security is improved, but cross-platform compatibility and operating system independence deteriorate
Solution Approach 1:
The patent introduces a virtualization layer as an intermediary between the operating system and network communications. This layer provides IPsec functionality without being dependent on any specific operating system, thereby maintaining communications security while achieving cross-platform compatibility. The virtualization layer acts as a mediator that implements encryption and security protocols independently of the underlying OS.
Solution Approach 2:
The patent segments the security functionality from the operating system by creating a separate virtualization layer. This segmentation allows the security protocols to be implemented in a platform-independent manner, resolving the contradiction between maintaining security reliability and achieving cross-platform versatility.
2Reliability
If traditional network defense methods are used, then basic security protection is provided, but proactive threat response and real-time monitoring capabilities are insufficient
Solution Approach 1:
The virtualization layer performs preliminary actions by establishing security protocols and authentication mechanisms before actual communications occur. It proactively monitors and controls network traffic in real-time, enabling threat detection and response before attacks can compromise the system, thereby improving both basic protection and real-time response capabilities.
Solution Approach 2:
The system implements feedback mechanisms through the virtualization layer that continuously monitor network communications and provide real-time information about potential threats. This feedback enables dynamic adjustment of security measures and proactive response to emerging threats, enhancing both basic protection and response productivity.
3Reliability
If point-to-point communications protection is implemented, then individual connection security is improved, but comprehensive network-wide security management and authentication schemes are insufficient
Solution Approach 1:
The virtualization layer provides universal security management that handles both point-to-point connection protection and network-wide security policies simultaneously. It implements multi-functional capabilities including authentication, authorization, accounting, and encryption across the entire network infrastructure, resolving the contradiction between individual connection security and comprehensive network management.
Solution Approach 2:
The patent merges individual connection security mechanisms with network-wide security management into a unified virtualization layer. This integration allows point-to-point encryption to work seamlessly with broader authentication and authorization schemes, achieving both connection-level and network-level security simultaneously.
Data Source
AI summary
A method includes receiving a data packet including a header having a structure from an operating system at a virtualization layer, where the virtualization layer is above a physical layer and below all other layers. The method also includes performing an operation on a portion of the data packet other than the header, thereby creating a modified data packet and maintaining the original header structure. The method further includes transmitting the modified data packet, including the original header structure, to the physical layer.
