A powerful solution to run application
in a trusted execution environment.

What is Samsung TEEgris?

Samsung TEEgris is a system-wide security solution which allows you to run applications in a trusted execution environment based on TrustZone. We present the TEEgris architecture for external developers to enable their trusted applications and services. Samsung Mobile uses the TEEgris framework for several commercial projects. You can utilize the TEEgris framework to run and deploy your applications. TEEgris supports TrustZone technologies and guarantees the strengths of security( i.e., hardware cryptography, binary encryption, access control) and performance( i.e., multicore, multithreading). In addition, TEEgris provides a variant of GlobalPlatform APIs such as Trusted User Interface, Trusted Storage, and so on. TEEgris provides end-to-end service deployment environments so you can write, manage, deploy trusted applications on TEEgris.
