Self-repairing active defense type true random number generating device and generating method

Abstract

The self-repairing active defense type true random number generation method obtains the physical quantity in nature as the input of the random quantity, performs statistical test operation and judgment according to the input random quantity and random state value, and the statistical result is used for adaptive random state prediction function correlation Update the parameters, and update the random state value; if the statistical result meets the threshold, the random state value will be updated; if the statistical result does not meet the threshold, an intrusion alarm will be triggered, and the random state value will be updated by the adaptive random state prediction function. The key derivation function outputs a true random number based on the updated random state. The present invention is applicable to the true random number generation of the resource-limited nodes of the Internet of Things, realizes the intrusion detection and alarm of the nodes, and realizes active repair or defense through the self-adaptive random state prediction function when the physical quantity acquisition of the nodes fails or is attacked. , increase the reliability of nodes or the difficulty of intrusion, and gain more response time for network security management.

Description

technical field [0001] The invention relates to the technical field of network security communication, in particular to a self-repairing active defense type true random number generating device and a generating method. Background technique [0002] In recent years, the rapid development of the Internet of Things has attracted widespread attention from all walks of life, and will completely change our lives in the near future. Low-cost, low-power and low-speed wireless sensor networks are an important part and key enabler of the Internet of Things, which can well solve the two key issues that hinder large-scale deployment of the Internet of Things, cost and energy consumption. Thousands of intelligent sensing or control nodes are connected to each other through a wireless sensor network to transmit sensing / monitoring information or control instructions. Massive wireless sensor network nodes often have the characteristics of low cost, low power consumption, and low speed, whi...
