Abstract: With the application field of FPGA constantly expanding,researches of downloading bitstream securely and reliably are also expanding.In the paper develops an FPGA-based circuit based on AES algorithm using SRAM and EFUSE storage to store Encryption KEY and two kinds of decryption circuits.The new design downloads the encryption bitstream to SRAM within the FPGA more efficiently,securely and flexibly.The new design is proved to be feasible and practical after the analysis of corresponding digital simulation waveform.
