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...

Examples

Embodiment Construction

[0021] see Figure 1 to Figure 3 , the system-level chip based on the method of the present invention includes a communication interface one, an encryption module and a communication interface two, the communication interface one and the encryption module are connected to each other, the encryption module and the communication interface two are connected to each other, the input terminal of the communication interface one and the communication interface two The output terminals of are respectively connected to the data path. Communication interface 1 and communication interface 2 adopt dual-port USB2.0, serial ATA, parallel ATA or Ethernet interface; the encryption module can adopt a symmetric algorithm with high security level and fast execution speed. The system-on-a-chip also includes a CPU controlling the communication interface 1, the encryption module, and the communication interface 2, and three random storage modules RAM1, RAM2, and RAM3 respectively corresponding to t...
