Abstract: A data processing host includes a program running environment and a first isolation environment. The first isolation environment is isolated from the program running environment. The host operates in a non-secure mode in the program running environment, and operates in a secure mode in the first isolation environment. The program running environment includes a virtual instance operating in the non-secure mode, and the first isolation environment corresponds to the virtual instance in the program running environment. The first isolation environment includes an operating system in the secure mode and a resource allocated to the first isolation environment and comprising a first isolation space for running the operation system and a secure processing program, which corresponds to a program in the virtual instance and is for processing to-be-processed data.
