Trusted Multi-Cloud Scheduling for Secure AK/SK Handling

The patent introduces a trusted execution environment (TEE) as an intermediary component between the multi-cloud service system and user information. The TEE acts as a secure mediator that handles encryption and decryption operations, isolating sensitive cryptographic operations from the main system. This resolves the contradiction by providing enhanced credibility through a dedicated security intermediary while managing complexity through modular architecture rather than distributed security measures across the entire system.

The patent segments the system into distinct functional modules: a multi-cloud service system, a trusted execution environment, and separate processing components for scheduling instructions and user information. By dividing the system into isolated segments with clearly defined interfaces, the patent enhances credibility through specialized security zones while managing overall system complexity through modular design. The TEE segment specifically handles sensitive operations, preventing complexity from propagating throughout the entire system.

The trusted execution environment automatically performs encryption and decryption operations without requiring manual intervention from users or administrators. The TEE self-manages sensitive cryptographic operations, including automatic key management and secure information handling. This resolves the contradiction by providing high security through automated cryptographic operations while maintaining ease of operation, as users interact with simplified interfaces rather than complex security procedures.

The TEE serves as an intermediary that shields users from complex security operations. Instead of requiring users to manually manage cryptographic keys and encryption processes, the TEE intermediary automatically handles these operations in the background. This maintains ease of operation for end users while implementing robust security measures through the intermediary's automated cryptographic processing.

The trusted execution environment acts as a specialized intermediary component that handles scheduling instruction processing in an isolated, secure manner. Rather than implementing complex security measures throughout the entire system architecture, the TEE intermediary provides enhanced credibility and transparency specifically for scheduling operations. This localized approach improves scheduling credibility without proportionally increasing overall system complexity.

The patent applies enhanced security and transparency measures locally to the trusted execution environment and scheduling processing components, rather than uniformly across the entire system. The TEE provides high-assurance processing specifically where scheduling decisions are made, while other system components maintain standard operational complexity. This local quality approach enhances scheduling credibility without unnecessarily increasing device complexity throughout the entire system.
