Introduction to the TPM protocol stack and tools (1)
tags: TPM software architecture TPM tools TPM
1. TPM related projects, there are several open source projects
Address:https://github.com/tpm2-software
2. Tpm2-software contains a total of four projects
tpm2-tools tpm2-tss tpm2-abrmd tpm2-tss-engine
3. tpm2-tools
This project provides users with several commands for using TPM resources, such as:
tpm2_create : Create a key
tpm2_sign : startup TPM, relative to initializing the TPM
tpm2_listpcrs: Print out all the pcrs values in the TPM
tpm2_send_command: can send byte stream commands
tpm2_hash : hash
etc.
４．tpm2-tss
This part of the TPM protocol stack is divided into two layers, one for the upper layer developer to provide and encapsulate a unified call interface, and the other for the upper layer to provide access to the underlying hardware resource interface.
５．tpm2-abrmd
pm2-abrmd is a background process, mainly for TPM hardware resource management. For example: when we are on the upper level
When applying the load key, don't worry, there is still a free key slot in the TPM, because the tpm2-abrmd background process will help us to do it. If the key slot in the TPM is not enough, then Will be swapped out without the key, and then used by the currently accessed process.
６． tpm2-tss-engine
This is an encryption-related engine that is not currently used and needs to be used with openssl.
7. The following figure looks at the architecture of the entire software layer
8. Compile dependencies must look at the INSTALL file
