Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic security paradigms face limitations in controlling access to information, especially in geographically dispersed and complex network environments, where existing access control mechanisms are inflexible and poorly suited to evolving access control requirements.
Innovation Solution
A security scheme that translates security language constructs into logic language constructs, enabling flexible specification and enforcement of decentralized authorization policies through a deterministic evaluation algorithm, ensuring efficient and guaranteed authorization query evaluations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional access control mechanisms (ACLs, policy-based mechanisms) are used, then authentication and authorization can be performed, but the system becomes inflexible and cannot adequately address evolving access control requirements in geographically dispersed networks
Solution Approach 1:
The patent replaces traditional mechanical access control mechanisms (ACLs, policy-based mechanisms) with a logic-based system using logic programming languages. This substitution enables the system to handle complex, evolving access control requirements through logical inference and rule-based reasoning, providing adaptability without proportionally increasing system complexity.
Solution Approach 2:
The patent changes the fundamental parameter of access control from static rule-based decisions to dynamic logic-based inference. By using logic programming with variables, constraints, and inference rules, the system can adapt to changing requirements by modifying logical parameters rather than restructuring the entire access control architecture.
2Productivity
If logic language constructs are used for security policy evaluation, then flexible and efficient authorization decisions can be made, but the translation and evaluation process adds computational overhead
Solution Approach 1:
The patent performs preliminary translation of security policies into logic language constructs before authorization queries are executed. This pre-compilation approach allows the system to optimize the logical representation once, then efficiently evaluate multiple authorization queries against the pre-processed logic rules, reducing per-query evaluation time and improving overall productivity.
Solution Approach 2:
The patent creates logical copies of security policies in a formal logic language representation. These logical copies can be efficiently manipulated and queried without affecting the original policy definitions, enabling rapid authorization evaluation while maintaining the integrity of the source security policies.

AI summary
Security language constructs may be translated into logic language constructs and vice versa. Logic resolution may be effected using, for example, the logic language constructs. In an example implementation, translation of a security language assertion into at least one logic language rule is described. In another example implementation, translation of a proof graph reflecting a logic language into a proof graph reflecting a security language is described. In yet another example implementation, evaluation of a logic language program using a deterministic algorithm is described.
