Focusing on the characteristics of the new high secure architecture of network computer, an operating system with internal network structure is designed. The operating system contains two subkernels: local kernel and network kernel, the two subkernels run individually in two subsystems. In order to communicate between two subsystems securely, an inter-subsystem private data transfer protocol is proposed and implemented in this paper. The private protocol is a connection-oriented protocol, it can provide reliable end-to-end connectivity Protocol format and protocol connection management based on signature verification are elaborated. Combining with shared transit cache which mounted on the shared bus, the private data transfer protocol can ensure data to be transferred safely and inerrably between subsystems. The effectiveness of the private data transfer protocol is verified by the results of final experiments.
