Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cryptographic solutions for network traffic encryption require complex setup processes and separate configurations for each destination, making it cumbersome for users and enterprises to ensure secure communication, especially when dealing with sensitive information.
Innovation Solution
A cryptographic proxy service that generates spoofed certificates for data destinations, allowing for end-to-end encryption and offloading security negotiations, while enforcing compliance with management and security policies to secure network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cryptographic solutions with certificates and key pairs are used, then security is provided, but setup complexity increases and separate configuration is required for each destination
Solution Approach 1:
The patent introduces a cryptographic proxy server as an intermediary between the user device and destination servers. The proxy server handles certificate generation, security negotiations, and encryption/decryption operations centrally, eliminating the need for users to manually configure certificates and cryptographic key pairs for each destination. This mediator approach resolves the contradiction by maintaining security through cryptographic mechanisms while significantly reducing setup complexity for end users.
Solution Approach 2:
The system implements automated certificate generation and security configuration through the cryptographic proxy server. When a user accesses a destination through the proxy, the server automatically generates appropriate certificates and cryptographic parameters without requiring user intervention. This self-service mechanism maintains robust security while eliminating manual setup steps, directly addressing the contradiction between security reliability and setup complexity.
2Reliability
If separate setup process is undertaken for each destination site, then security is customized per destination, but time consumption increases
Solution Approach 1:
The cryptographic proxy server provides universal security services that work across multiple destination sites through a single configuration. The server generates destination-specific certificates and handles security negotiations for various destinations using a unified architecture. This multi-functional approach allows the system to maintain customized security for each destination while eliminating the need for separate setup processes, directly resolving the time consumption issue.
Solution Approach 2:
The system performs preliminary cryptographic setup operations automatically through the proxy server before users need to access destinations. Certificates, cryptographic key pairs, and security parameters are pre-generated and configured by the proxy server in advance. This preliminary action ensures security is already in place when users access destinations, eliminating setup time while maintaining destination-specific security requirements.
3Ease of operation
If cryptographic proxy service is implemented, then ease of operation improves, but system complexity increases
Solution Approach 1:
The patent extracts complex cryptographic operations from the user device and relocates them to a dedicated cryptographic proxy server. The proxy server handles certificate management, encryption, decryption, and security negotiations, while the user device only needs to establish basic connections. This extraction improves ease of operation for users while consolidating system complexity into a specialized server component rather than distributing it across multiple devices.
Data Source
AI summary
A cryptographic proxy service may be provided. Upon determining that data associated with a network destination comprises at least some sensitive data, a cryptographic service may provide a security certificate associated with the network destination. The plurality of data may be encrypted according to the security certificate associated with the network destination and provided to the cryptographic service for re-encryption and transmission to the network destination.
