Runtime Cryptographic API Evaluation for Unsafe Call Detection

The patent introduces an intermediary component (cryptography manager or policy enforcement module) that sits between the application and the Cryptography Architecture API. This intermediary monitors, evaluates, and controls cryptographic API calls based on security policies, allowing legitimate operations while blocking unsafe ones. The intermediary acts as a mediator that preserves both ease of operation for valid calls and cryptographic security through active intervention.

The patent integrates multiple functions into a single cryptography manager component: it serves as both a monitoring system that tracks cryptographic API calls and a policy enforcement mechanism that evaluates and controls those calls. By combining monitoring, evaluation, and enforcement functions in one universal component, the system achieves improved cryptographic security without proportionally increasing overall system complexity.

The patent implements a feedback mechanism where the cryptography manager continuously monitors cryptographic API calls, evaluates them against security policies, and provides real-time control decisions. This feedback loop allows the system to maintain high productivity by permitting valid cryptographic operations while simultaneously identifying and blocking harmful cryptographic vulnerabilities, thus resolving the contradiction between productivity and security risks.
