9 5 Andreas Steffen
In order to connect to a TPM 2.0 hardware or firmware device, the TSS2 software stack developed by Intel is needed. Because the official Ubuntu *tpm2-tss* package is rather outdated (e.g. since version 0.98 the TCTI interface to the TPM 2.0 resource manager has changed several times), strongSwan is currently based on a recent version directly drawn from the TPM2-TSS git repository https://github.com/01org/TPM2.0-TSS. Avoid any TCTI interface incompatibilities by fetching the latest *tpm2-tools* version from https://github.com/01org/tpm2.0-tools as well.

Build and install both the *tpm2-tss* stack and the *tpm2.0-tools*, start the *tpm2-resourcemgr* as a service in the background and try to connect to the TPM 2.0 by listing e.g. the contents of the SHA-1 bank of PCR registers

241 49 Andreas Steffen
Many certification authorities issue certificates based on PKCS#10 certificate requests. This approach is also possible. First a certificate request is generated on the host the TPM resides on
242 47 Andreas Steffen
<pre>
243 50 Andreas Steffen
 pki --req --keyid 0x81010004 --dn "C=US, O=TNC Demo, OU=AIK ECC, CN=raspi5.example.com" --san raspi5.example.com > ak_ecc_req.der
244 47 Andreas Steffen
</pre>
245 49 Andreas Steffen
When you are prompted for a smartcard PIN just press <enter> since this TPM private key is not protected by a PIN. In a second step the CA issues the AIK certificate based on the PKCS#10 certificate request
246 49 Andreas Steffen
<pre>
247 47 Andreas Steffen
pki --issue --cacert demoCaCert.pem --cakey demoCaKey.pem --type pkcs10 --in ak_ecc_req.der --lifetime 3651 > raspi5_ak_ecc_Cert.der

h2. Store the ECC AIK Certificate in the NV RAM of the TPM
251 54 Andreas Steffen
252 55 Andreas Steffen
A TPM 2.0 has a certain amount of Non Volatile Random Access Memory (NV RAM) that can be used to store arbitrary data, e.g. the X.509 certificates matching the persistent keys. IF both the certificates and keys are persisted in the TPM then the system disk of the host can be reformatted at any time without loosing the machine or user credentials.As with smartcards the needed amount of memory must be reserved first so we check the size of the X.509 ECC certificate
