   insmod tzdriver

   /usr/bin/teecd &

2. Write the test CA and TA. Ensure that the TA code does not contain the test CA permission information. Compile, deploy, and run the test CA and TA. (See Expected Result 2.)
3. Write the test CA and TA. Ensure that the CA requests invoking multiple TAs, and the code of each TA contains CA permission information. (See Expected Result 3.)
4. Write the test CA and TA to test the mode in which multiple CAs access a single TA. Ensure that the code of each requested TA contains all CA permissions. (See Expected Result 3.)
