Can you count the letter c in:
== Physically secure == ORWL natively supports full hard drive encryption, and we enable this by default. The cryptographic key is generated inside of a high-security microcontroller, and we store this key in a manner that causes it to be deleted in the event that any kind of physical tampering of the system takes place. What this means to you is there is simply no way to dissect the system in a manner that will allow attacker to read your data. In addition to the hard drive encryption, your operating system and the whole Intel platform that runs it cannot even receive power without going through the security subsystem. The secure microcontroller handles initial boot and perform integrity checks on firmwares before powering up anything else. It is attached directly to the NFC, the accelerometer, and the OLED display. When the user presents one of their NFC key fobs to the reader, and the microcontroller authenticates it, the Intel portion of the system will be powered up and handed the hard drive cryptographic key.

ORWL is only computer to disconnect USB and HDMI ports until user is 2 factor authenticated and user is present (less than 10m from device). This is managed by secure controller before Intel is booted. So there is no ME engine attacks possible unless user is present and insert something rogue onto the ports…It is important to consider that the ME engine datasheet is not public so any SW solution to any engine attack is not proven to be enough. <span style=font-size:110%;>[https://www.youtube.com/watch?v=aiMNbjzYMXo Video: What is AMT Attack ]</span> [[FILE:IntelAmtAttacks.png|center]] - USB attacks. There are other entry point to a machine by using USB in some of the multiple functionality small USB computers can simulate. <span style=font-size:110%;>[https://www.youtube.com/watch?v=gHqIIU-Ys6M Video: Existing USB /HID Attacks / Tools ]</span> [[FILE:HACKLU USB.png|center]] - All keys (users ID, SSD encryption keys…) are stored in secure controller. This prevent many attacks such as TPM die opening, and low level attacks on boot or Bios. (SGX for instance is not protected) Keys are released only when user are authenticated.

These attacks can be performed over the air as presented in this video or using SDA / DPA analysis if attacker can monitor power supply line. So any VPN, login key or encryption keys are exposed on PC without this. https://www.youtube.com/watch?v=4L8rnYhnLt8 and power analysis on Wikipedia A great deal more details on the security features are available in [[Security]].
