Multi-layered Packet Security via Header Identifier Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional network communication systems rely on a single set of rules for packet handling, which limits flexibility and efficiency, as every packet is subjected to the same security measures at each routing device, leading to increased processing resources and reduced control over packet communications.
Innovation Solution
The implementation of multi-layered packet security, where a packet header is modified to include an identifier that determines which set of rules to apply, allowing network hosts or routing components to configure different security levels for packets as they traverse the network, enabling multiple sets of rules to be applied based on specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of rules is applied to all packets at each routing device, then security consistency is maintained, but processing resources are increased and flexibility is reduced
Solution Approach 1:
The patent segments the single set of rules into multiple sets of rules (first plurality and second plurality), where each set corresponds to different security rings or network domains. Packets are assigned to specific rule sets based on their origin and destination, allowing selective application of security measures rather than uniformly applying all rules to every packet.
Solution Approach 2:
The patent implements local quality by applying different security rule sets to different packets based on their specific characteristics (source, destination, security ring). Each packet receives tailored security handling appropriate to its local context rather than a blanket approach, optimizing processing resources while maintaining necessary security.
2Adaptability or versatility
If multiple sets of rules are applied to packets based on different security rings, then control over packet communications is improved, but device complexity is increased
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple sets of rules in the routing component before packet transmission. Each rule set is prepared in advance for specific security rings or network domains, allowing the routing component to quickly match packets to appropriate rules without complex real-time decision-making, thus managing device complexity while maintaining fine-grained control.
3Productivity
If every packet is subjected to the same security measures, then security consistency is maintained, but processing efficiency is reduced
Solution Approach 1:
The patent implements universality by creating a framework where multiple rule sets serve different security rings but are managed through a unified routing component. The routing component universally handles packets by referencing identifiers and selecting appropriate rule sets, maintaining security consistency across different network domains while improving processing efficiency through selective rule application.

AI summary
Methods and media for multi-layered packet security control are described. In one embodiment, a header of a packet is modified to include an identifier that identifies a manner in which the packet should be subject to a particular set of a plurality of sets of rules. The particular set of rules dictates how the packet is to be handled. Further, in one embodiment, the packet is communicated to a routing component, and the routing component is configured to reference the identifier to determine which, if any, of the plurality of sets of rules to apply to the packet.
