Half of the encryption key is stored on the TPM chip and the other half is stored on the computer hard drive, so if the TPM chip is removed, the computer will not boot. If the computer is not in a trustworthy state, it will not boot, meaning there is no way to access or extract any data from the computer. it has not been tampered with), it will operate normally. If the computer is in a trustworthy state (i.e. When you boot a computer, TPM checks the state of the computer and the state of the computer's environment. To accomplish this, a discrete chip is designed, built and evaluated for the highest level of security that can resist tampering with the chip, including probing it and freezing it with all sorts of sophisticated attacks." TCG explains that Discrete TPM protects your device from being hacked, "via even sophisticated methods. It ensures that no unintended users gain access to your data by either stealing your computer or hard drive or via a software attack or brute force attack. Once activated, a user may notice a slower boot up process with the OS.Ī TPM chip safeguards the data on your computer. It will not affect the computer in anyway, the chip will lay dormant, until activated. Many computers, including several product lines from Teguar, come with a TPM chip by default, but the TPM is inactive until it is enabled in the BIOS. This blog will focus on Discrete TPM, because it is the most common and the most secure form.ĭiscrete TPM is in the form of surface mount integrated circuit and is mated to the computer's motherboard. There are five types of TPM: Discrete, Integrated, Firmware, Software, and Virtual. The current version is TPM 2.0, which is standardized under ISO/IEC 11889. Trusted Computing Group (TCG) created TPM in 2003. This blog provides an overview of TPM and how it is used in industrial and medical computers. TPM is widely accepted as the most secure method of protecting information stored on a computer. This is especially important for industrial, medical and enterprise computers, which can store massive amounts of company data or sensitive patient information. It provides a higher level of security than software alone and protects your data from hackers, malware and thieves. TPM secures your data with an algorithm integrated into your computer hardware. Trusted Platform Module (TPM) chips are used in all types of computers from personal laptops, to business computers, to industrial panel PCs, to medical computers.
