The proliferation of mobile platform business has given rise to a variety of security problems, and the TEE (such asT6) and application protection (such as TVEE) are considered to be cutting-edge and most effective to protect the security of application and sensitive data. TEE builds a new security environment from the hardware bottom to ensure key application data security, while mobile applications protect their business security through application-level protection. However, the starting point of both TEE and application protection is that the security of current mobile platform OS(such as Android, iOS, Linux, etc.) cannot be guaranteed. Is it true that the giant modern OS is not secure enough? The OS itself runs at the processor privilege level, which is considered to be the highest running level of the system. However, in reality, processors now have a higher level of privilege - the virtualization layer. This level has not been utilized to improve the security of the overall system.

TrustKernel's Trusted Hyper Execution Environment, THEE, is designed to solve the problems of the operating system’s own security problem, and is currently the most advanced technology of mobile system security. By utilizing ability of the processors’ highest authority to perform isolation and interception of keys events in the system. It comprehensively protects the system from hardware to application layer, by monitoring and verifying events of the OS, filtering all malicious operations happening on the kernel state and with key data.
