Description

technical field

[0001] The invention belongs to the technical field of remote certification of computer information, and in particular relates to a log-based certification method and system for embedded device control flow. Background technique

[0002] With the continuous development of embedded systems, all kinds of embedded systems have penetrated into all aspects of people's production and life, playing an increasingly important role, especially in some such as medical equipment, industrial control systems, embedded devices play a vital role. Due to the increasing value involved, embedded systems are increasingly becoming targets for system disruption by attackers.

[0003] Remote attestation technology is an important way to verify the integrity of remote devices. It usually includes two roles: verifier and prover. The prover is usually one or more remote devices, and the verifier is a server that wants to obtain the integrity of the remote device. The remote attesta...
