Realization of High-Performance Confidential Data Transmission Based on FPGA

This paper uses advanced encryption standard (AES) to implement encryption algorithm and FPGA devices to achieve hardware encryption. AES commonly used to provide several security services such as data confidentiality. However, it is a challenge to design efficient hardware architectures with small hardware resource usage. The system is implemented in hardware environment using Verilog HDL. The method has the advantage of full hardware circuitry and can update its own cryptographic algorithm module. Hardware encryption system is based on cryptographic devices and appropriate software program. FPGA can modify the hardware programming repeatedly, its flexibility and scalability make it enable to meet this demand in the encryption field, and reduce costs and improve security. The logic circuit module of cryptographic algorithm has a high flexibility in design, because users can define a specific structure of the cipher algorithm module.
