For details refer to the man page of the command.

Create the request on a trusted system.


		trusted:~$ pvattest create −k hkd.crt −−cert CA.crt −−cert ibmsk.crt −−arpk arp.key −o attreq.bin

On the SE-guest, perform the attestation.


	seguest:~$ pvattest perform attreq.bin attresp.bin

On a trusted system, verify that the response is correct. Here, the protection key from the creation and the SE-guest’s header is used to verify the measurement.


	trusted:~$ pvattest verify −i attresp.bin −−arpk arp.key −−hdr se_guest.hdr
	trusted:~$ echo $?
	0

If the measurements do not match pvattest exits with code 2 and emits an error message. The SE-guest attestation failed.


	trusted:~$ pvattest verify −i wrongresp.bin −−arpk arp.key −−hdr se_guest.hdr
	ERROR: Attestation measurement verification failed:
	Calculated and received attestation measurement are not the same.
	trusted:~$ echo $?
	2
