bios mo kuai zai ji suan ji an quan xi tong zhong de ying yong yan jiu

With the development of computer network has been the rapid development of network information security in all walks of life,more and more attention by the majority of users,from the whole network information security to the security and confidentiality of communications of one computer has become a research focus. At present, the research on single computer information security has produced results,can be divided into three aspects:the research focuses on the data integrity and confidentiality to the integrity and credibility of system research,research and service. According to the above research put forward a design scheme of BIOS module of the bottom of the computer input and output security system based on the information provided by the use of cryptography, identity identification and data encryption and other means to provide integrity checking the validity of the computer system,the user identification and hard disk data protection,security services on single computers.
