Method for processing secret data based on virtualization and trusted platform module in network system, and computer readable recording medium

摘要

PURPOSE: A data security processing method and a record media thereof are provided to improve security by dividing a business domain and a security domain through a virtualization technique. CONSTITUTION: The hash value generated in a first trust platform module(224) of a client terminal(212) is transmitted. The client terminal is authenticated based on the hash value received from a server(200). A virtual machine is transmitted to the client terminal. The client terminal accesses a confidential data storage unit(208) through a security domain based on the virtual machine. The server encodes the confidential data through a second trust platform module(210) of the server. The server stores the encrypted confidential data in a confidential data storage unit.
