Abstract

The invention is suitable for the field of information security, and provides a user data protection method for a secure computer. The method comprises the following steps: establishing a secure storage space, and controlling the access right of the secure storage space; and enciphering instructions related to the secure storage space, and performing certification processing and decipherment on the instructions on the receiving end of the instruments. The method effectively prevents hacker interception software from intercepting transmitted instructions by enciphering and deciphering user data information of the secure storage space and the transmitted instructions for various times and performing validity certification by issuing credible authorization certificates between a transmitting part and a receiving part of the instructions, so as to guarantee the security of the user data information.

Description

Technical field [0001] The invention belongs to the field of information security, and in particular relates to a method for protecting user data of a secure computer. Background technique [0002] At present, with the continuous development of computer technology, the ensuing information security issues have attracted more and more attention. As the carrier of information, computers face various information security issues. For example, hacker attacks, virus intrusions, denial of service, etc. from the network bring information security threats; there are also vulnerabilities in computer management and computer access control. Information loss caused by insufficient strength; and security risks caused by the management of storage devices for high-confidential information. [0003] With the maturity of trusted computing technology, the popularization of high-strength biometric technology, the connection of underlying hardware devices, the continuous improvement of Unified Extensi...
