Routing Tokens Secure Cloud Service Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a secure connection between a client and a server in a cloud service environment is computationally difficult and resource-intensive due to the need to identify and map the network path through multiple intermediary devices, often requiring significant processing and storage resources, and existing methods may compromise data security by decrypting and re-encrypting packets at each node.
Innovation Solution
The use of routing tokens is introduced to specify and validate the network path between a service node and a server, allowing each network device to identify and pass the initial packet to the next node, establishing an end-to-end cryptographic context that secures the connection without decrypting or re-encrypting data at intermediary devices, thus reducing computational load and enhancing security.

Engineering Contradiction Analysis
1Reliability
If packets are encrypted and transmitted through multiple intermediary network devices, then data security is maintained, but it becomes computationally difficult and expensive to map out the network path between server and client
Solution Approach 1:
The patent segments the routing information into separate routing tokens that are embedded within packets. Each intermediary network device extracts and processes only its specific routing token, rather than analyzing the entire packet structure. This segmentation simplifies the network path mapping process while maintaining security through end-to-end encryption.
Solution Approach 2:
The patent introduces routing tokens as intermediary elements that facilitate communication between the server and client through multiple network devices. These tokens act as mediators that carry routing information without requiring the intermediary devices to perform complex decryption or path analysis, thus reducing computational complexity while preserving security.
2Reliability
If existing methods are used to secure connections through multiple network devices, then data can be transmitted, but security may be compromised by decrypting and re-encrypting packets at each node
Solution Approach 1:
The patent establishes an end-to-end cryptographic context in advance between the server and client before data transmission begins. This preliminary action allows packets to be encrypted once at the source and decrypted once at the destination, eliminating the need for repeated decryption and re-encryption at each intermediary node, thus reducing computational resource consumption while maintaining security.
Solution Approach 2:
The patent extracts the cryptographic context establishment from each intermediary node and concentrates it only at the endpoints (server and client). By taking out the decryption and re-encryption operations from the intermediary devices, the system reduces computational energy loss while preserving connection security through end-to-end encryption.
3Ease of operation
If routing tokens are provided to each network device to specify the network path, then packet forwarding is simplified, but the initial setup requires distributing tokens to multiple devices
Solution Approach 1:
The patent merges the routing information and cryptographic context into a unified structure where routing tokens are embedded within the encrypted packets themselves. This combining approach allows the tokens to be distributed along with the data flow, simplifying the setup process compared to separate token distribution systems, while maintaining ease of packet forwarding at each node.

AI summary
Systems and methods for establishing a secure connection are described. A server receives a plurality of routing tokens for establishing a service connection between a service node and the server along a network path through a plurality of network devices. The routing tokens can be validated by a corresponding network device. The server transmits a packet including the routing tokens to a first network device. The first network device validates a first routing token associated therewith, then directs the packet along the network path to a second network device, and so forth, until each of the network device receives and validates their routing token. The server establishes a cryptographic context between the service node and server for establishing a secure channel between the service node and the server. The server transmits a service node routing token to the service node via the secure channel for validation.
