Embedded smart devices are widely used in people s life, and the security problems of embedded smart devices are becoming more and more prominent. Meanwhile lots of methods based on software have been presented to boot the system safely and ensure the security of the system execution environment. However, it is easy to attack and destroy the methods based on software, which will cause that the security of the system cannot be guaranteed. Trusted Computing Group proposed the method of using Trusted Platform Module (TPM) to authenticate the credibility of the platform, which can solve the disadvantages of using methods based on software to protect the system. However, due to the limited resource and volume of embedded smart devices, it is impossible to deploy TPM on embedded smart devices to ensure the security of the system operating environment. Therefore, a novel trusted boot model for embedded smart devices without TPM is proposed in this paper, in which a device with TPM provides trusted service to realize the trusted boot of embedded smart devices without TPM through the network and ensure the credibility of the system execution environment.
