Abstract

The invention relates to the field of trusted computing, and particularly provides a terminal integrity detecting and proving method and device based on trusted computing for solving problems in the prior art. On the condition of not increasing additional hardware requirements and special instructions, an isolated and safe integrity dynamic measurement environment is built for an application program, and parallel barrier-free operation of other application programs in the measurement process is ensured. In the integrity proving process, the actual measurement value of each component in a computing terminal is concealed, and the problem that a hacker decode the version, configuration, firmware and other information of the terminal through the actual measurement values is effectively prevented; when the trusted computing terminal is subjected to integrity detection, extension integrity measurement values and the total measurement frequency stored in a platform configuration register PCR are sent to a verifier after being signed, and the verifier can detect the integrity of the trusted computing terminal by executing hash operation.

Description

technical field [0001] The invention relates to the field of trusted computing, in particular to a method and device for measuring and proving the integrity of a trusted computing terminal. Background technique [0002] With the rapid development and in-depth application of computer network technologies such as cloud computing, Internet of Things, and mobile Internet, the three most prominent security threats are malicious code attacks, illegal information theft, and illegal destruction of data and systems. Information-targeted malicious code attacks surpass traditional viruses as the biggest security threat. [0003] Traditional network security protection methods such as firewalls, intrusion detection, virus defense, and network isolation all focus on passively protecting the information security of networks and servers. The relatively fragile terminal has increasingly become a weak link in the security of information systems. In response to these system security require...
