METHOD, HOST AND APPARATUS FOR PROCESSING DATA

A data processing method, a data processing host, and a data processing apparatus are provided and pertain to the IT field. The host includes a program running environment (1) and a first isolation environment (2), the program running environment (1) is an environment in which the host operates in a non-secure mode, and the first isolation environment (2) is an environment in which the host operates in a secure mode; the program running environment (1) includes at least one virtual instance (11) operating in the non-secure mode, and the first isolation environment (2) corresponds to the virtual instance (11) in the program running environment (1); and the first isolation environment (2) includes an operating system in the secure mode and a resource allocated to the first isolation environment (2). The resource includes a first isolation space and a processor resource. The first isolation space is used to run the operating system and a secure processing program, and store to-be-processed data. The secure processing program corresponds to a program in the virtual instance (11) and is used to process the to-be-processed data. The first isolation space is isolated from the program running environment (1). This can improve data processing security.
