Application Access Ticket System for Secure Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern computing and communication devices face challenges in securely managing access to secure resources such as cryptographic keys and secure data folders, as existing methods often require frequent user authentication, which can be inconvenient and inefficient.
Innovation Solution
A system and method that generates and uses tickets associated with secure resources and applications, allowing for secure access without constant user prompting, by using message authentication codes and digital signatures, and ensuring tickets are time-limited and tied to specific applications and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is required for every access request to secure resources, then security is improved, but user convenience and system efficiency deteriorate due to frequent prompts
Solution Approach 1:
The system performs preliminary authentication by obtaining user permission in advance and generates a ticket that encapsulates this authentication result. The ticket is then reused for subsequent access requests to the same secure resource, eliminating the need for repeated authentication prompts while maintaining security.
Solution Approach 2:
The patent introduces a ticket as an intermediary element between the user and the secure resource. The ticket serves as a mediator that carries authentication information and application identification, allowing the system to verify access rights without directly prompting the user for each request.
2Reliability
If user authentication is required for every access request to secure resources, then security is improved, but system efficiency deteriorates due to repeated authentication processes
Solution Approach 1:
The system performs preliminary authentication by obtaining user permission in advance and generates a ticket that encapsulates this authentication result. The ticket is then reused for subsequent access requests to the same secure resource, eliminating the need for repeated authentication prompts while maintaining security.
Solution Approach 2:
The patent creates a copy of the authentication result in the form of a ticket. This ticket contains essential information (application ID, resource ID, timestamp, signature) that replicates the authentication verification process, allowing efficient reuse without重新 performing the full authentication sequence.
3Ease of operation
If access control is simplified to improve user convenience, then ease of operation is improved, but security control over secure resources deteriorates
Solution Approach 1:
The ticket implements local quality by containing specific, targeted information for each access scenario (application ID, resource ID, timestamp). This allows the system to verify exactly what is needed for each specific access request without requiring broad, complex authentication mechanisms, achieving both simplicity and security.
Solution Approach 2:
The patent changes the parameter of authentication from a static password-based system to a dynamic ticket-based system with multiple parameters (application ID, resource ID, timestamp, signature). This allows the system to adapt security verification to the specific context of each access request, maintaining security while simplifying the user experience.
4Adaptability or versatility
If multiple applications can access secure resources independently, then application versatility is improved, but security management complexity increases
Solution Approach 1:
The ticket serves as a universal access credential that can be used by any application that has been granted permission. The same ticket structure and verification process works for all applications and secure resources, providing a multi-functional solution that handles diverse access scenarios without requiring separate security mechanisms for each case.
Solution Approach 2:
The patent segments the security management into distinct components: application identification (application ID), resource identification (resource ID), temporal validation (timestamp), and cryptographic verification (signature). This segmentation allows the system to independently verify each aspect of access rights, managing complexity through modular verification rather than monolithic security checks.
Data Source
AI summary
A system and method for controlling access to a secure resource in a device are disclosed. In some embodiments, the device may include a processor capable of receiving a first request from a first application of a plurality of applications executable by the processor, where the first request requests access to the secure resource, and the first request identifies the plurality of applications. In response to the first request, the processor is capable of generating a ticket associated with the secure resource and with each of the plurality of applications, and then storing the ticket in a memory. After receiving a second request from a second application requesting access to the secure resource, the processor is capable of granting the second application access to the secure resource, if the ticket associated with the secure resource exists and if the ticket is associated with the second application.
