Trustonic and Mimer jointly offers a secure architecture for data management using Mimer SQL and Trustonic’s Trusted Execution Environment. Trustonic is a world-class provider of cybersecurity solutions for protecting smartphones, critical mobile apps, wearables, IoT devices, healthtech and automotive systems.

Mimer SQL is using a Trusted Application running inside Trustonic’s Trusted Execution Environment. The database encryption key is stored in a hardware isolated secure storage, well protected from potentially malicious code running in the rich execution environment. This solution has several advantages – the key is protected but also easily accessible for the Mimer server to use when needed. The security is increased substantially with almost no loss in performance.

Kinibi is Trustonic’s Trusted Execution Environment operating system which can execute Trusted Applications on a device using ARM TrustZone technology. The TEE is used to protect and isolate sensitive assets, such as sensitive code or information. Kinibi has been integrated in over one billion devices of smartphones, tablets, laptops, and IoT devices

To solve the problem of database encryption key storage, Mimer SQL is leveraging Trustonic’s Trusted Execution Environment (TEE), Kinibi, to provide a hardware isolated secure storage for the encryption key. All code execution that uses the key, such as encryption and decryption, is executed by Mimer’s Trusted Application running in the TEE. This way, the key is protected from potentially malicious applications or code running in the Rich Execution Environment. Mimer’s Trusted Application is also completely isolated from other Trusted Applications that may exist in the TEE. The architecture of the solution can be seen in figure 1 below.
