Abstract
For high security laptop or PC, TPM is the security kernel of modern computer which includes
important data, for example, key or pins. However, there are many reports show it can be
hacked by software or physical attacking. Current TPM are slightly harder to attack, but not
very much harder. Infineon, TPM IC provider, commented that they knew this was possible due
to the high skill level necessary for success. Here we introduce a method to protect it by a micro
switch sensor with a firmware in EC.
