An Efficient Data Transmission Protection Method for IoT Terminals Based on Temporary Ciphertext Stream Resource Pool

Industrial IoT terminals are sensitive to device costs, which limits the application of high-performance encryption modules with PCIE and USB interfaces. Currently, security chips (or modules) are generally used to encrypt data, and this method has a long processing delay for large amounts of data. The present invention optimizes data encryption and decryption, integrity protection strategies and processes by constructing a temporary ciphertext data stream resource pool to meet the needs of high real-time and high bandwidth data secure transmission in industrial Internet of Things application scenarios. Experience has shown that this solution significantly improves data encryption and decryption efficiency while ensuring economic and business security.
