A data security protection mechanism for IoT terminal equipment based on multi-system collaboration based on cryptographic security module

Abstract

Based on domestic cryptographic algorithms, this research encrypts the data of multi-system collaborative IoT terminal devices, and the data is transmitted in ciphertext to realize the security protection of massive structured and unstructured data; using database encryption and decryption, file system encryption and decryption and other passwords Technology to ensure data storage and data transmission security, to achieve data confidentiality, integrity and availability.
