| Abstract: | This paper presents a solution of a high speed, low-cost and reconstructable encryption engine based on the AES encryption aiming to solve the balance problem of hardware resources and circuit performance in commercial encryption engines. According to FPGA inherent structural features, the four-level pipeline structure is improved and the encryption module is described with VHDL. By expanding the password encryption engine, the goal of real-time, reconstructability and security is achieved. Compared with some other encryption engines, this encryption engine has a good safety performance guarantee, speed and resources performance ratio. |
