Solution Overview
Problem
Cloud computing environments face challenges in providing specialized computing resources while maintaining security and availability, as users' access to configurable hardware can introduce risks of malfunction, data corruption, or denial of service due to faulty or malicious designs.
Innovation Solution
A logic repository service that manages configuration data for configurable hardware, using cryptographically signed and encrypted data to program user-designed logic, with host logic acting as a sandbox to ensure compatibility and security, and a cryptographic engine for decryption and validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are granted access to configurable hardware to execute specialized computing tasks, then adaptability and computing performance are improved, but security and system reliability deteriorate due to risks of malfunction, data corruption, or denial of service from faulty or malicious designs
Solution Approach 1:
A logic repository service acts as an intermediary between users and configurable hardware. This service validates user-submitted logic designs before deployment, encrypts configuration data, and manages the configuration process. The intermediary prevents direct access to hardware configuration mechanisms, thereby blocking malicious or faulty designs from compromising system reliability while still allowing specialized computing tasks to execute on adaptable hardware
2Ease of operation
If configuration data is stored in plaintext for easy access and modification, then ease of operation is improved, but security deteriorates as malicious designs can be injected and distributed to affect other users
Solution Approach 1:
The system transforms configuration data from plaintext to encrypted form using cryptographic algorithms. This parameter change in data representation maintains security by preventing unauthorized modification and injection of malicious designs, while the encryption/decryption process managed by the logic repository service preserves operational capability through automated key management and validation procedures
3Reliability
If cryptographic validation and encryption processes are implemented for configuration data, then security and reliability are improved, but device complexity and processing overhead increase
Solution Approach 1:
The logic repository service automates cryptographic operations including key generation, encryption, decryption, and validation without requiring manual intervention. The system self-manages the complexity of cryptographic protocols and key management infrastructure, presenting a simplified interface to users while maintaining high security standards through automated processes
