TPM
Pre-install TPM-tools
$ sudo apt install --yes tpm2-tools
(1)產生randon code
$ sudo su
root@linux:/home/ubuntu# tpm2_getrandom --hex 20
(2) 對指定檔案 msg.dat 加密
root@linux:/home/ubuntu# tpm2_createprimary -C p -c platform_primary.ctx root@linux:/home/ubuntu# tpm2_create -C platform_primary.ctx -G rsa2048 -u key.pub -r key.priv root@linux:/home/ubuntu# tpm2_load -C platform_primary.ctx -u key.pub -r key.priv -c key.ctx root@linux:/home/ubuntu# echo "my test" >msg.dat root@linux:/home/ubuntu# tpm2_rsaencrypt -c key.ctx -o msg.enc msg.dat root@linux:/home/ubuntu# cat msg.enc root@linux:/home/ubuntu# tpm2_rsadecrypt -c key.ctx -o msg.ptext msg.enc root@linux:/home/ubuntu# cat msg.ptext root@linux:/home/ubuntu# cat msg.dat
(3) 將資料儲存至 tpm 內存
root@linux:/home/ubuntu# tpm2_nvdefine -Q 0x1500031 -C o -s 32 -a "ownerread|policywrite|ownerwrite" root@linux:/home/ubuntu# echo "write_tpm_adv" > adv.data root@linux:/home/ubuntu# tpm2_nvwrite -Q 0x1500031 -C o -i adv.data root@linux:/home/ubuntu# tpm2_nvread -Q 0x1500031 -C o -s 32 -o read.data root@linux:/home/ubuntu# cat read.data
(4) 確認已經寫入儲存區域
root@linux:/home/ubuntu# tpm2_nvreadpublic > nv.out root@linux:/home/ubuntu# cat nv.out
Error
ERROR: Esys_NV_DefineSpace(0x14C) - tpm:error(2.0): NV Index or persistent object already defined ERROR: Failed to create NV index 0x1500031.
