AI Technical Summary

Problems solved by technology

[0004] (1) Weak security

[0005] In the traditional safe and trusted design scheme, the security of the system is mainly realized through separate boards. Many key parameters and key security processing and calculation processes are directly exposed on the separate boards, which are particularly vulnerable to physical attacks. Reverse engineering attacks, cloning attacks, etc.

[0006] (2) Low reliability

Especially in the field of special applications, the environmental adaptability and reliability requirements for temperature, humidity, vibration, etc. are very high, and the traditional design scheme cannot fundamentally guarantee the reliability of the design

[0008] (3) Higher cost

[0009] In the traditional safe and trusted design scheme, its hardware design cost, development cost, hardware debugging cost, hardware maintenance cost, etc. are all very high
