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 Because the official Ubuntu *tpm2-tss* package is rather outdated (e.g. since version 0.98 the TCTI interface to the TPM 2.0 resource manager has changed several times), strongSwan is currently based on a recent version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

h2. Derive a Persistent RSA Endorsement Key
118 1 Andreas Steffen
119 25 Andreas Steffen
The following tpm2-tools command derives a 2048 bit RSA Endorsement Key (EK) in a deterministic way from the secret _Endorsement Primary Seed_ *unique* to each TPM device and makes the key persistent in the non-volatile memory of the TPM under the object handle 0x81010001
120 11 Andreas Steffen
121 24 Andreas Steffen
 tpm2_getpubek -H 0x81010001 -g 0x0001 -f ek_rsa.pub
122 9 Andreas Steffen
123 27 Andreas Steffen
The EK public key stored in the ek_rsa.pub file is encoded in a TPM 2.0 proprietary format but the key can be exported from the TPM in the regular PKCS#1 format using the *pki* tool
124 9 Andreas Steffen
125 50 Andreas Steffen
 pki --pub --keyid 0x81010001 --outform pem > ek_rsa_pub.pem
126 9 Andreas Steffen

h2. Generate a Persistent RSA Attestation Key
135 11 Andreas Steffen
136 12 Andreas Steffen
A 2048 bit RSA Attestation Key (AK) bound to the EK with handle 0x81010001 can be created and made persistent under the handle 0x81010002 with the following tpm2-tools command
137 1 Andreas Steffen
138 46 Andreas Steffen
 tpm2_getpubak -E 0x81010001 -g 0x0001 -D 0x000B -s 0x0014 -k 0x81010002 -P 123456 -f ak_rsa2.pub -n ak_rsa2.name
139 12 Andreas Steffen
140 46 Andreas Steffen
This AK key is protected by the PIN (-P parameter) *123456*. The AK public key can now be exported in PKCS#1 format from the TPM using the *pki* tool
141 12 Andreas Steffen
142 50 Andreas Steffen
 pki --pub --keyid 0x81010002 --outform pem > ak_rsa_pub.pem

165 13 Andreas Steffen
166 13 Andreas Steffen
A 256 bit ECC Attestation Key (AK) bound to the EK with handle 0x81010003 can be created and made persistent under the handle 0x81010004 with the following tpm2-tools command
167 13 Andreas Steffen

h2. Issue an RSA AIK Certificate
261 41 Andreas Steffen
262 42 Andreas Steffen
Based on the RSA AK public key exported from the TPM, the following *pki* command generates an Attestation Identity Key (AIK) certificate signed by the Demo CA
263 41 Andreas Steffen
<pre>
264 41 Andreas Steffen
pki --issue --cacert demoCaCert.pem --cakey demoCaKey.pem --type pub --in ak_rsa_pub.der --dn "C=US, O=TNC Demo, OU=AIK RSA, CN=raspi5.example.com" --san raspi5.example.com --lifetime 3651 > raspi5_ak_rsa_Cert.der

h2. Issue an ECC AIK Certificate
268 41 Andreas Steffen
269 42 Andreas Steffen
Based on the ECC AK public key exported from the TPM, the following *pki* command generates an Attestation Identity Key (AIK) certificate signed by the Demo CA
270 41 Andreas Steffen
<pre>
271 41 Andreas Steffen
pki --issue --cacert demoCaCert.pem --cakey demoCaKey.pem --type pub --in ak_ecc_pub.der --dn "C=US, O=TNC Demo, OU=AIK ECC, CN=raspi5.example.com" --san raspi5.example.com --lifetime 3651 > raspi5_ak_ecc_Cert.der

274 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
275 47 Andreas Steffen
<pre>
276 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
277 47 Andreas Steffen
</pre>
278 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
279 49 Andreas Steffen
<pre>
280 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
284 54 Andreas Steffen
285 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
286 54 Andreas Steffen
<pre>
287 54 Andreas Steffen
ls -l raspi5_ak_ecc_Cert.der

289 54 Andreas Steffen
</pre>
290 54 Andreas Steffen
291 54 Andreas Steffen
We then define a memory location with a size of 449 bytes that can be accessed via the handle 0x01800004 which is also called the NV index
292 54 Andreas Steffen
<pre>
293 54 Andreas Steffen

294 54 Andreas Steffen
</pre>
295 54 Andreas Steffen
296 54 Andreas Steffen
Then we write the certificate file to the NV RAM destination
297 54 Andreas Steffen
<pre>
298 54 Andreas Steffen
