+# Trust Platform Module
+
+## Description
+Trust Platform Module(TPM) is a physical or embedded security technology
+(microcontroller) that resides on a computer's motherboard or in its processor.
+TPMs use cryptography to help securely store essential and critical information
+on PCs to enable platform authentication.
+
+The Intel® PTT is an integrated TPM that adheres to the 2.0 specifications
+and offers the same capabilities of a discrete TPM, only it resides in the
+system’s firmware, thus removing the need for dedicated processing or memory
+resources.
+
+TPM2 smoke test: test_smoke.sh
+```

+TPM2 space content test: test_space.sh
+```

+TPM2 sync test: test_async.sh
+```
+# python3 -m unittest -v tpm2_tests.AsyncTest
+test_async (tpm2_tests.AsyncTest) ... ok
+test_flush_invalid_context (tpm2_tests.AsyncTest) ... ok
+
+----------------------------------------------------------------------
+Ran 2 tests in 0.004s
+
+OK
+```
+
+## Expected result
+All test results should show pass, no fail.
