In the data era, encrypted storage of files is a basic requirement for data security. Because most computing devices and storage devices lack data protection functions or their own data protection ability is poor, the data stored in them are at risk of being stolen. To solve this problem, this paper proposes an authentication storage scheme based on embedded Internet of things devices, which uses the Trusted Cryptography Module (TCM), mutual authentication technology, asynchronous file transfer technology, and disk partition encryption technology to realize the security storage function of host-side files on the device-side storage device, and enhances the security through the three security mechanisms of mutual authentication technology, access control of encrypted partition and state inspection of the encrypted partition. The function modules of the system based on the hardware platform of the Internet of Things are implemented and evaluated in this paper. The average experiment time of two-way authentication is 3242.42 ms. The result shows that the system has strong security and a good transmission rate.
