II The design of AES encryption circuit based on Verilog HDL Abstract Nowadays , the puter technology is in a rapid development in the direction of fast and portable in the information society . This means that the electronic form of data and personal information is widely used by us . Therefore , the work information security has aroused people’s attention . The way of how to keep the private information away from the outside world to steal has became the focus of the scholars study now . This topic is put forward in the background I mentioned before in purpose that design a circuit of AES encryption based on Verilog HDL . There are serval tasks to be done according to the subject , including the principle of AES encryption algorithm in the process of analysis and the subsequent hardware implementation . Firstly , the core of the design of AES encryption circuit is the implementation of AES encryption algorithm . Therefore , this article introduces the principle of AES algorithm , including the Sbox 、 shiftrows、mixcoloumns and AES line ranks , etc . Secondly , this paper pared the AES encryption circuit module partition and introduced Verilog HDL description and Modelsim simulation one by one . Finally , it gives the design process of use Synopsys DC and Astro to finish the prehensive and automatic wiring . Key Words : AES 。設(shè)計 AES 加密電路的核心就是 AES 加密算法的實現(xiàn)。因此， 網(wǎng)絡(luò)信息安全 這個名詞逐漸進(jìn)入人們的眼球。 畢業(yè)設(shè)計報告 (論文 ) 基于 Verilog HDL 的 AES 加密電路設(shè)計 所屬系 電子工程 系 專 業(yè) 電子科學(xué)與技術(shù)
