TCTI-CMD(7) TPM2 Software Stack TCTI-CMD(7) NAME tcti-cmd - TPM2 Sub-process Command TCTI library SYNOPSIS A TPM Command Transmission Interface (TCTI) module for interaction with a sub-process. DESCRIPTION tcti-cmd is a library that abstracts the details of direct communica- tion with the interface and protocol exposed by a sub-process that can receive and transmit raw TPM2 command and response buffers. The inter- face exposed by this library is defined in the "TSS System Level API and TPM Command Transmission Interface Specification" specification. EXAMPLES For example, if you wanted to use the tpm2_send(1) command as the sub- process to send data to and from the TPM, one could do so like this: tpm2_getrandom -T "cmd:tpm2_send -s" --hex 4 A more useful example would be connecting to a remote machine using ssh and interacting with the remote machine's TPM as if it were local. This uses tpm2_send(1) on a remote machine and uses ssh as the sub-process to create the tunnel to the remote machine. If encrypted sessions are used, the remote machine is blinded to the TPM data and cannot inter- pose on that traffic. tpm2_getrandom -T "cmd:ssh remotehost tpm2_send" -s --hex 4 AUTHOR TPM2 Software Project <https://github.com/tpm2-software/tpm2-tss> SEE ALSO Tss2_Tcti_Device_Init(3), Tss2_Tcti_Socket_Init(3), Tss2_TctiLdr_Ini- tialize(3), Tss2_TctiLdr_Finalize(3), tcti-device(7), tcti-socket(7), tcti-tabrmd(7), tpm2-abrmd(8) COLOPHON This page is part of release 4.0.1 of Open Source implementation of the TCG TPM2 Software Stack (TSS2).
