Authorization Component Token Validation for Communication Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional techniques for handling access to communication services and associated application servers are inefficient, inaccurate, or insufficiently accurate, allowing unauthorized access and compromising security by sharing private decryption keys and subscriber-related information with less trusted or untrusted application servers.
Innovation Solution
The system employs an authorization component that generates an encrypted token with device identifier information, which is validated by the authorization component using a private decryption key, cryptographic algorithm, and initialization vector, ensuring only authorized communication devices and users access the service while minimizing the information shared with application servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional techniques share private decryption keys and subscriber information with application servers, then service access is simplified, but security is compromised
Solution Approach 1:
The patent introduces an authorization component as an intermediary between communication devices and application servers. This component validates tokens and manages authorization without requiring application servers to directly handle sensitive cryptographic materials, thus maintaining security while enabling service access.
Solution Approach 2:
The patent extracts sensitive cryptographic information (private decryption keys and subscriber-related information) from the application server environment and stores it securely in the authorization component. This separation allows service access to proceed without exposing sensitive data to potentially untrusted application servers.
2Adaptability or versatility
If cryptographic information is shared with application servers, then service functionality is enhanced, but unauthorized access risk increases
Solution Approach 1:
The authorization component acts as a mediator that enables service functionality through token validation without requiring application servers to possess or handle cryptographic information. This intermediary approach maintains service versatility while eliminating the security vulnerability of sharing cryptographic materials with untrusted parties.
Solution Approach 2:
The patent segments the authorization system into distinct functional components: token generation, token validation, and service delivery. The cryptographic validation functions are separated from the application server layer and placed in the dedicated authorization component, reducing the attack surface while maintaining service functionality.
3Measurement precision
If subscriber information is stored centrally, then access control is improved, but system vulnerability increases
Solution Approach 1:
The patent extracts subscriber-related information from the application server environment and stores it in the authorization component. This extraction improves access control accuracy by ensuring information is stored in a dedicated security context, while the modular design prevents system-wide vulnerability by isolating the sensitive data storage to a specific component.

AI summary
Authorization for access to an application server and associated communication service can be desirably managed. When a device attempts to access an application server and service, an authorization server generates an encrypted token, comprising device identifier information, and communicates the token to the device. The device communicates the token to the application server. The application server communicates the token to the authorization server. The authorization server determines whether the device is validated to access the application server and service based on the encrypted token, private decryption key, and initialization vector, and based on subscriber-related information. The authorization server does not share the private decryption key or initialization vector with the application server. If validated, the authorization server communicates validation-related information, including a permitted portion of subscriber-related information, to the application server. If not validated, the authorization server communicates not-validated information to the application server.
