Research on Data Integrity Detection Method Based on Security Perception Layer of Internet of Things Architecture

摘要

In order to realize the data integrity security of the IoT nodes, and comprehensively consider the calculation performance and energy consumption issues, the improved CRC redundancy check algorithm is used to perform data integrity detection, and a method for detecting the integrity of the data transmission and reception of the IoT node is given. This solution provides an effective plan and basis for protecting data integrity in the Internet of Things environment. The data integrity security detection method of the Internet of Things based on the improved CRC model is improved on the basis of the CRC inspection algorithm. The improved detection algorithm is integrated into the operation of the node to receive and send data, which can realize the Internet of Things environment. Data integrity security detection can protect data integrity in wireless sensor networks.
