The keymaster function affects the performance of secure os. When considering the swtiching time of the normal world < - > Secure world and the processing delay of the SecureOS by the scheduling policy of the normal world, it is necessary to increase the time.
Even though Secure world is no problem, Sometimes there is a possibility of that the test will fail because it is a limited resource normal world.
On average, it is performed in a very fast time, but sometimes it takes a lot of time. After many tests, the safe time was measured.

This test verifies that verification tokens with different time stamps do
not have the same MAC. This may not guarantee that the MAC is computed
correctly but it catches implementation that do not include the time
stamp in the mac.
It also checks that the MAC changes when both time stamp and challenge
changes.
Test: yes it is
