Client-Side Transmission Authentication With Encrypted Validation Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in securely authenticating client-side devices without exposing API keys, which can be compromised, and existing time-based authentication methods require user interaction and are vulnerable to automated attacks.
Innovation Solution
A method using a time-based algorithm with a trusted server to generate a derived key, session ID, and metadata, encrypting these with a static API key, and transmitting an encrypted validation object to a processing server for authentication, ensuring secure and automated access without exposing the API key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If API keys are provided for client-side transmissions, then authentication is simplified, but security is compromised as keys can be stolen
Solution Approach 1:
The patent introduces a time-based algorithm as an intermediary between the client-side device and the API key. Instead of directly using the API key for authentication, the system generates a time-based validation object that incorporates the API key indirectly. This intermediary mechanism allows authentication to occur without exposing the API key to client-side devices, thereby maintaining security while preserving ease of operation.
Solution Approach 2:
The patent implements dynamic authentication by using time-based algorithms that generate validation objects changing with each request. The validation object incorporates time-sensitive components that prevent reuse and make static API key exposure ineffective. This dynamic approach ensures that even if an API key is compromised, the time-based validation mechanism prevents unauthorized access.
2Reliability
If time-based authentication algorithms are used, then security is improved, but user interaction is required and automated attacks remain vulnerable
Solution Approach 1:
The patent implements self-service authentication where the client-side device automatically generates time-based validation objects without requiring user intervention. The system performs authentication tasks autonomously by incorporating time-based algorithms that automatically validate requests. This eliminates the need for user interaction while maintaining the security benefits of time-based authentication and preventing automated attacks.
3Reliability
If server-to-server communication is implemented, then security is improved by avoiding API key exposure, but the process becomes more complex and automated attacks remain possible
Solution Approach 1:
The patent segments the authentication process into distinct components: time-based algorithm generation, validation object creation, and server verification. By breaking down the authentication mechanism into these segments, the system achieves server-to-server communication security without excessive complexity. Each segment handles a specific aspect of authentication, making the overall process more manageable while maintaining security against automated attacks.
