Abstract


The advent of the information society to the global opportunity for the rapid development of information technology . Computer technology has aroused great changes of production, lifestyles and ideas and personal PC application , which greatly promoted the development of human society and the progress of human civilization . However, it brought enormous benefits to enjoy fast information system at the same time , is also facing a severe test of information security . Because information security is not only related to whether personal privacy can be protected even related to national security and interests , to protect the security of information systems has been used as an important issue by more and more people 's attention . Hard disk encryption card for the security of data in the hard disk . This paper focuses on the working principle of the IDE hard disk interface , agreement, read and write timing and DES encryption algorithm used to analyze the security of the algorithm . On this basis , the following research : (1) hard disk encryption card overall design , simulation and performance analysis and design components . (2) complete hard disk encryption card interface design that satisfies both IDE hard disk interface timing DES encryption module data input / output requirements . (3) on the basis of in -depth study of the DES encryption algorithm , DES algorithm FPGA implementation and design the corresponding optimization .
