Network service providing platform based on high safety information system

Abstract

The invention provides a network service providing platform based on a high safety information system. The network service providing platform comprises an information processing part, a control part, a second storage part and a network connection part, wherein the control part contains a hardware switch; the hardware switch at least contains two states, namely a first state and a second state; atleast one control signal wire of the information processing part, used for performing write operation on the second storage part is connected with the second storage part through the control part; when the hardware switch is in the first state, the control part cuts off the connection of the control signal and the signal wire of the second storage part; when the hardware switch is in the second state, the control part maintains the connection of the control signal and the signal wire of the second storage part; the network connection part is connected with the information processing part; andthe hardware switch is in the first state before the information processing part runs a network connection program. The network service providing platform can be used to effectively prevent the attacks of hackers and viruses.

Description
