AI Technical Summary

Technical Problem

In existing technologies, random number generation, power consumption control, and quality verification are separated, making it impossible to coordinate adjustments based on feedback from the environment and the quality of the data itself. This results in the entropy source being unable to proactively adapt to dynamic changes in the external operating environment, and the power consumption mode becoming detached from the security and quality of random numbers, lacking a closed-loop feedback mechanism.

Method used

By collecting physical process data such as thermal noise, clock jitter, and power ripple in parallel, combined with environmental interference monitoring, the entropy source weight is dynamically adjusted, the quality of random numbers is verified in real time, and the system power consumption mode is switched in a coordinated manner to form a closed-loop control mechanism.

Benefits of technology

It enables the random number generation process to actively adapt to the external environment, ensuring output stability and security. The close integration of power consumption control and quality verification improves the system's security and power efficiency in complex environments.

Abstract

The application relates to the fields of chip-level security technology and electric digital data processing, and discloses a method and system for anti-interference low-power-consumption random number generation and real-time verification, which comprises the following steps: collecting multiple-source entropy data and environment monitoring data in parallel, dynamically adjusting the weight of the entropy source according to the environment data through a cooperative scheduling mechanism, and dynamically regulating the power consumption of the system according to the real-time verification result and the task priority, and completing the hardware verification and abnormal interception before the random number output. The application changes the random number generation from a static preset configuration into a dynamic self-reconstruction process which can actively adapt to the external environment changes, the core security of the application comes from the dynamic adaptation ability of the whole multi-source system rather than the robustness of a single entropy source, the matching between the system power consumption input and the security output is realized, and the stable reliability of the random number in a complex embedded scene is improved.
