Trusted Application Life Cycle
Following are some details on the expected behavior of the Intel® DAL TEE in CSE platforms and rules specifying when
installJTA
and open session need to be called:- Install Java* Trusted Application (JTA) is persistent until uninstall; this means that it survives power state transitions (S0-Sx, S0-G5).
Note:
Some security-related metadata is stored persistently even after the JTA has been uninstalled.- JTA must be installed before you can open a session.
- Open session:
- Survives S0 –>S0ix-Connected standby power state (the host application does not need to open a new session to the trusted application when the platform resumes).
- Does notsurvive S0 –>Sx standby power state (the host application needs to open a new session to the trusted application when the platform resumes).
