This paper proposes a secure computing architecture based on the dual hard disk and dual system switching (D 3 S), and provide the mechanism of sensitive data copy and transmission processing for the two operating environments of the computer. It can not only provide a secure computing environment for all processing links involving sensitive files, but also resist various possible malicious attacks. The experimental simulation results show that the D3S architecture has obvious performance advantages in both the data delivery ratio and the memory computing overhead. When the size of the copied sensitive file is 50MB, the copy time overhead of D 3 S is 1.12s. The secure transmission rate of sensitive data of D 3 S architecture is significantly better than that of other existing architectures, which has been maintained at about 8.5 Mbps.
