MesaTEE is the next-gen solution to enable general computing service for security-critical scenarios. It will allow even the most sensitive data to be securely processed to enable offshore businesses without leakage.
The solution combines the advanced Hybrid Memory Safety (HMS) model and the power of the Trusted Computing technologies (e.g. TPM) as well as the Confidential Computing technologies (e.g. Intel® SGX).
The emerging technologies of big data analytics, machine learning, cloud/edge computing, and blockchain are significantly boosting our productivity, but at the same time they are bringing new confidentiality and integrity concerns. On public cloud and blockchain, sensitive data like health and financial records may be consumed at runtime by untrusted computing processes running on compromised platforms; during inhouse data exchange, confidential information may cross different clearance boundaries and possibly fall into the wrong hands; also not to mention the privacy issue arises in offshore data supply chains.
Although the consequences of data breaching have been extensively elaborated, we should also note that proprietary computing algorithms themselves, such as AI models, also need to be well protected. Once leaked, attackers can steal the intellectual properties, or launch whitebox attacks and easily exploit the weakness of the models.
Facing all these risky scenarios, we are in desperate need of a trusted and secure mechanism, enabling us to protect both private data and proprietary computing models during a migratable execution in potentially unsafe environments, yet preserving functionalities, performance, compatibility, and flexibility. MesaTEE is targeting to be, as we call it, the full “Universal Secure Computing” stack, so it can help users resolve these runtime security risks.
Figure 1: MesaTEE stack redefines future AI and big data analytics by providing a trusted and secure offshore computing environment. The confidentiality and integrity of both data and code can be well protected even if clients and service/platform providers do not trust each other.
As illustrated in the Figure 1, the confidentiality and privacy of data and models can be well protected with MesaTEE, even if data and model originate from different parties with no mutual trust. Moreover, the computing platform itself is not necessarily trusted either. The Trusted Computing Base (TCB) can thus be largely reduced to MesaTEE framework alone.

The open-source version of MesaTEE is a prototype. The code is constantly evolving and designed to demonstrate types of functionality.
