Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trusted computing chip and high-speed encryption chip are used separately with independent key systems, then security functions are complete, but hardware costs and management costs are high
Solution Approach 1:
The patent combines trusted computing chip and high-speed encryption chip into a single integrated chip that contains both key systems. The trusted computing chip stores trusted computing keys while the high-speed encryption chip stores encryption keys, but both chips are integrated on the same substrate and can share resources. This merging reduces the number of separate hardware components and simplifies key management architecture, thereby reducing both hardware costs and management complexity while maintaining complete security functions.
Solution Approach 2:
The integrated chip design enables the chip to perform multiple security functions - both trusted computing operations and high-speed encryption operations - within a single device. The chip can switch between different key systems and cryptographic algorithms as needed, providing universal security capabilities that eliminate the need for separate dedicated chips for each function, thus reducing overall system complexity and cost.
2Reliability
If two separate chips are used for trusted computing and encryption, then specific security functions are optimized, but key management complexity increases
Solution Approach 1:
By integrating both trusted computing and encryption key systems into a single chip, the patent creates a unified key management architecture. The chip contains separate secure storage areas for trusted computing keys and encryption keys, but manages them through a unified interface and control mechanism. This reduces key management complexity by eliminating the need to manage separate key systems across multiple independent chips, while still providing optimized security functions for both trusted computing and encryption operations.
3Adaptability or versatility
If separate key systems are maintained for trusted computing and encryption chips, then functional independence is preserved, but hardware costs increase
Solution Approach 1:
The patent merges two previously separate chips into one integrated chip that maintains distinct functional areas for trusted computing and encryption. Each functional area has its own secure key storage and processing capabilities, preserving functional independence. However, the integration allows for shared resources such as communication interfaces, power management, and physical security features, thereby reducing overall hardware costs compared to using two completely separate chips.

AI summary
A data processing method based on an integrated chip is provided. The method includes providing computing information of a trusted computing chip to a high-speed encryption chip, and invoking the high-speed encryption chip to perform data encryption or trusted computing based on the computing information. As such, after these two types of chips are integrated, these two types of secure computing (the trusted computing and the data encryption) can share common computing information. Compared with using individual sets of computing information before integration, corresponding hardware and management costs are reduced. Moreover, the trusted computing chip is superior to the high-speed encryption chip in terms of functional integrity and reliability for data encryption functions. Storing the computing information by the trusted computing chip can improve the security of the data encryption. For trusted computing functions, the utilization of the computing power of the high-speed encryption chip is increased, and the computational efficiency of the trusted computing is improved.
