This is the TPM’s anti-hammering feature, depending on TPM version 1.2 or 2.0 it will close for a given period of time.Ĭryptographic Processor: this is a zone with mathematical compute + cryptographic compute. If you try too many times telling the mummy the wrong secret word, the mummy gets angry and kicks you out, closing that one single door for x amount of time. So if your MBAM or AD did not save it during the initialization of the TPM there is no way of retrieving it ever again. Once it is set you cannot retrieve it anymore.

The Owner Password is also non-exportable. if you share the owner password, consider your entire device as compromised. Only one Owner can exist, resulting in one Owner Password. In order to use or read anything inside the TPM chip, you need to authenticate first, this with your Owner Password, to proof you own this device. Secured I/O: The mummies Hall way! here you will find your door-keeping mummy and you have to tell him the secret word. the mummies are safeguarding your pyramid and its treasures, and the only way to allow anyone into the pyramid is when you whisper the secret word.īitLocker will try to facilitate, and do this for you if not done yet.a Password is set and is ready for use.this specific secret word is then agreed upon and as of then the mummies will start guarding your pyramid and treasure on your behalf. When you initialize the TPM, basically you show the mummies you have recently purchased the Pyramid and the only way to get in is to use a specific secret word.The Pyramid is visble, but the mummy is safely inside, behind the only door inside, with the door closed of course.No owner password is set, you need to initialize the TPM.Basically the Pyramid is hidden in the sand, and all mummies in a hybrid sleep.The TPM chip is disabled, you need to enable it in the BIOS.if you don’t initialize the TPM, the only door into the pyramid is basically closed, the mummy resting inside the first room, locked away. if you don’t know the pyramid, the mummy will not allow you in. So, basically, there is a mummy in front of the only entrance into the pyramid, asking you for the secret word, before it allows you in. If your TPM has no password, you cannot pass through the Secure Input/Output. Owning a device will result in generating an Owner Password on the chip. Initializing it means you will tell the TPM chip you own the device and therefor you are allowed to compute against it. Enabling the TPM chip is not enough, it will not act if you don’t proceed initializing it. if you enable it, your OS can retrieve its details.
Why these steps? Well, first of all, like any other device listed in the BIOS you can decide if you want to use or not. Once the TPM is initialized you can start using it. Then the TPM is enabled, yet not operational. First you need to make sure it is enabled in the BIOS. To make the TPM Chip operational you need to go through a few steps. The ones I will be explaining is the BitLocker-Game and TPM Attestation-Game.Īs for the specs… let’s have a look at the pyramid from the inside: If you pass all the rooms, the puzzle pieces will you give the map to the treasure!Įach method you use has its own gameplay. If you manage to play the game/exam correctly in each room, you get a piece of the puzzle. Each door can cause a trap, resulting in eventually being thrown out by the mummy of the entire pyramid, the door being closed and locked for a few hours. Each room and door has a an exam/game you need to play and win before you can get go closer to the treasure room. See the TPM as a mythical pyramid with lots of rooms and doors, where you want to safely get into the Treasure room. The TPM Chip, also known as the Trusted Platform Module is a hardware security module on your motherboard, designed by the Trusted Computing Group Consortium. Welcome back, before I can proceed with either Windows Boot Process or Secure Certificate (TPM Attested Certificate) usage I need to explain a bit more about the TPM Chip.
