Password protection system based on hardware virtualization

Abstract

The invention provides a password protection system based on hardware virtualization, which aims at the current situation that a traditional password protection system cannot defend an inner nuclear layer rootkit. The password protection system based on hardware virtualization deploys a password protection module and a scheduling management module in an inner nuclear layer of an operation system, provides a safe input environment and an interactive interface, and simultaneously deploys an instruction intercepting module and an inner core protection module in a manager layer of a virtual machine. The instruction intercepting module is used for intercepting privileged instructions, and transmitting the current privileged instruction information to the inner core protection module so as to lead an execution flow path to enter a manger of the virtual machine from the inner nuclear layer of the operation system. The inner core protection module prevents the rootkit from randomly modifying nuclear data and service in the operation system, and guarantees password protection in the inner nuclear layer of the operation system. The password protection system based on hardware virtualization moves a trusted computing base (TCB) from the inner nuclear layer of the operation system to the manager layer of the virtual machine, thereby achieving lower level and higher safety.

Description

technical field [0001] The invention belongs to the field of computer system security, and in particular relates to a novel password protection system based on hardware virtualization. Background technique [0002] With the continuous development of the Internet, network applications and services have emerged and penetrated into people's daily life, but the network security situation is not optimistic, various hacking Trojan horse activities are frequent, and the intrusion methods are becoming more and more complex. Inadvertently, confidential information such as the user's online game password and even online banking password will disappear, seriously damaging user privacy and digital property security. The key reason why these account hacking Trojans can easily steal users' password information is that they use keyloggers. According to the keylogging implementation level, it is divided into two categories: [0003] (1) Application layer keylogging: illegally use the keyb...

Problems solved by technology

[0008] The present invention aims at the shortcomings that the traditional password protection is implemented in the operating system kernel, the security is not high enough, and the kernel layer rootkit attack cannot be prevented, and a password protection system based on hardware virtualization is proposed, which solves the problem while providing the password protection function. The problem of rootkit attacks at the kernel layer makes password protection more secure and flexible
