To solve these problems, this paper uses a digital signature technology and B/S architecture approach to ensuresystem data integrity while ensuring data confidentiality, authenticity, non-repudiation, etc. The system can achieve the functions ofthe course selecting management, curriculum management, the management of the elective course grade, public and private keysmanagement, signature verificationI Keywords courses selecting system; digital signature; B/S architecture: anti-denying(上接第50页)FPGA Implementation of Advanced Encryption Standard AES AlgorithmWen Zhangbin Yan HuizhongCInformation Technology Research Institute of Jinan University, Guangzhou 510075, Guangdong[Abstract] This paper introduces the AES(Advanced Encryption Standard) Algorithm, as well as the correlative concept and basicoperation of finite-field. AES encryption algorithm module is an important part of sccurity systcm, its corc mission is to encrypt thcdata. AES block cipher algorithm is widely used in research and development modules for its high efficiency, low overhead, simplefeatures such as the current passwordKoywardsI AES; Rijndael; block encryption algorithm; FPGA; round transformation53
