Method for high-speed data stream encryption transmission based on system-on-chip

Abstract

The present invention provides a method for high speed data stream encryption transmission based on system-on-chip, relating to the field of computer technology. The present invention comprises the following steps: first, in period n, receiving packet a through communication interface one and storing it in RAM1, encrypting packet b of RAM2, transmitting information of encrypted packet d of RAM3 through communication interface two; second, in period n+1, encrypting packet a of RAM1, transmitting information of encrypted packet b of RAM2 through communication interface two, receiving packet e through communication interface one and storing it in RAM3; third, in period n+2, transmitting information of encrypted packet a of RAM1 through communication interface two, receiving packet c through communication interface one and storing it in RAM2; encrypting packet e of RAM3. The invention with the characterization of high reliability and high transmission speed accomplishes data encryption and high-speed transmission by adopting hardware module in system-on-chip SOC.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a system-level chip-based high-speed data stream encryption transmission method. Background technique [0002] With the development of computer technology, mobile storage devices have gradually become the main way of information transmission instead of paper, and paperless office has gradually become the main way of office for industry users; with the rapid development of modern industries such as e-commerce, digital management and mobile office, Industry users (government, enterprise, military, secret-related agencies) have higher and higher data security requirements for secure communication and mobile storage devices. However, there are many potential safety hazards in mobile media. Random copying of data, arbitrary printing of data, loss of mobile media, etc. can lead to information leakage or theft; the invasion of viruses and hackers makes Internet information transmissio...

AI Technical Summary

Problems solved by technology

[0003] At present, the data flow encryption equipment for secure mobile storage and secure communication on the market mainly adopts software encryption or data segmentation encryption. These methods are low in security and are easy to be broken. They are not suitable for governments, military forces, secret agencies and enterprises. Carrying, storage and transmission of important data by industry users with high security requirements

Another solution for secure mobile storage devices uses the method of real-time data transfer by the CPU. Although this method is safer than the previous method, its speed is greatly reduced, only 400KB / s, and 20MB / s for mobile storage devices. The speed requirement is far from enough
