Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In reconfigurable networks where nodes discover connected neighbors and communicate over diverse subnets, existing technologies face challenges in securely and efficiently transporting data point-to-point, especially when network configurations change dynamically.
Innovation Solution
The method involves maintaining inbound and outbound routing tables, establishing secure communication links using tokens that change with each communication, and negotiating encryption keys and session nonces to ensure secure and flexible data transmission across hardware or wireless links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If nodes discover connected neighbors and communicate over diverse subnets in a reconfigurable network, then network adaptability is improved, but routing complexity increases
Solution Approach 1:
The patent changes the parameter of routing identification from static IP addresses to dynamic token values. Each node generates unique token values for different communication contexts, allowing the network to adapt to reconfigurations without complex routing logic. The token parameter encapsulates routing information, simplifying the routing decision process while maintaining adaptability.
Solution Approach 2:
The patent introduces tokens as intermediary elements that mediate between network topology changes and routing decisions. Instead of directly managing complex routing tables that update with topology changes, nodes use tokens as intermediaries that carry routing information, decoupling the routing logic from topology management and reducing overall system complexity.
2Reliability
If secure communication links are established with multiple nodes in a dynamic network, then security is improved, but communication overhead increases
Solution Approach 1:
The patent makes the token structure universal and multi-functional. Each token serves multiple purposes: it provides security authentication, carries routing information, and enables communication state tracking. This eliminates the need for separate security handshakes and routing table lookups, reducing communication overhead while maintaining strong security.
Solution Approach 2:
The patent performs preliminary security setup by pre-generating token values and establishing cryptographic relationships before actual data transmission. Nodes pre-compute token states and store them in routing tables, so that during communication, security verification is already in place and does not require time-consuming real-time computations.
3Reliability
If tokens change with each communication to prevent unauthorized access, then security is improved, but processing complexity increases
Solution Approach 1:
The patent segments the token into distinct portions: a first portion representing the token state and a second portion representing cryptographic material. This segmentation allows independent processing of routing decisions (using the state portion) and security operations (using the cryptographic portion), reducing overall processing complexity while maintaining security through frequent token changes.

AI summary
Systems and methods for token secured routing and discovery in token secured routing are disclosed. An inbound routing table is maintained. A communication link is established with a second node via a first port. A discovery packet is sent to the second node via the first port. A token is generated for communication with the second node. A first inbound routing entry is added to the inbound routing table, wherein the first inbound routing entry maps the first token state to the second node.
