Stopping the attack of hackers and preventing the information leak of on-line terminals have become the important task in the field of information security.Now the scheme of physical separation of network information based on the double hard disks is more ado-pted,but it costs much.The scheme of physical separation between two networks on single hard disk is discussed.Firstly,the structure and chain of partition table of hard disk is studied,and then a scheme of information physical separation on on-line terminals of single hard disk is brought forward,and the mechanism and method of physical separation between two networks is discussed,and the method and flow of control programs is introduced.The products designed according to this scheme are installed and used in many units in our country and are welcome.It achieves the goal of low cost and high security in information physical separation between two networks on on-line terminals.
