Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The present invention provides a static attribute remote proof method based on multiple measurements of the control flow model, such as figure 1 As shown, the steps of the method specifically include:

[0026] S1. The service provider formulates rules for the static attributes during task operation according to the user's security requirements, and generates a policy certificate;

[0027] S2. The mobile terminal obtains a policy certificate, and executes policy control; the policy control is that the mobile terminal performs access control on the terminal operating system based on the policy certificate and the control flow model;

[0028] S3. The mobile terminal measures and remotely proves the static attributes of the measurement points in the running process; the measurement points are consistent with the control points in ...

Abstract

The invention provides a static attribute remote attestation method based on multi-measurement of a control flow model. The method comprises the steps as follows: S1, a service provider makes rules for static attributes during task run so as to generate a policy certificate according to the safety requirement of a user; S2, a mobile terminal acquires the policy certificate and implements policy control, wherein the policy control means that the mobile terminal performs visit control to a terminal operation system, based on the policy certificate and the control flow model; and S3, the mobile terminal performs measurement and remote attestation to static attributes of a plurality of measurement points during task run. The static attribute remote attestation method can be used for performing multiple measurements and remote attestation to static attributes, solves the problem of static attribute attestation of password service parts of a trusted computing platform, and can ensure that the attestation can embody the state of the system more accurately and can conform to the expectation of the user.

Description

technical field [0001] The invention relates to the technical field of computer and electronic information, in particular to a static attribute remote proof method based on multiple measurements of control flow model BPCF. Background technique [0002] Verifying that the computing environment is secure and trustworthy is an important goal of trusted computing. With the development of technology, security threats on mobile terminals are also increasing. Research shows that 800,000 people were infected with malware every month in 2011 on the Android platform alone. Traditional anti-virus, intrusion detection and other security mechanisms also rely on the security support of the underlying operating system. Trusted computing technology achieves the purpose of ensuring computer security and reliability by enhancing the overall security of the entire computing system from the root of trust to trusted hardware, to trusted operating systems, and to trusted applications. "Trusted...
