Design of Gigabit Ethernet data encryption transmission system based on C6657 DSP

Abstract： Industry 4.0 has an unprecedented demand for the use of industrial Ethernet, and the security problem of Ethernet data transmission is also increasingly prominent. Based on TMS320C6657 Gigabit Ethernet and AES encryption algorithm, this paper designs a data encryption transmission system for Gigabit Ethernet. Use TMS320C6657 Gigabit Ethernet interface and off-chip PHY chip to complete the design of Gigabit Ethernet hardware interface, and complete the design of communication interface software in combination with NDK network development package. The encryption efficiency of AES algorithm in TMS320C6657 is studied, and the efficiency optimization of gigabit Ethernet data encryption transmission system is completed through the on-chip IPC module. Experiments show that the design can effectively improve the security of gigabit Ethernet data transmission.
