Rather, Tin Hat aims towards the ideal of guaranteeing zero information loss should the attacker physically acquire the box - either the adversary is faced with no file system to even begin cracking, or if any non-ephemeral memory is found, the adversary should not be able to tell if he is looking at encrypted data or random noise. This is certainly true in the case of unencrypted file systems, and at least potentially true in the case of encrypted. Tin Hat was conceived as a challenge to the old mantra that physical access to a system means full access to the data. Needless to say, this has some rather extreme advantages and disadvantages, making Tin Hat a rather particular distribution. One pays the prices of long boot times (5 minutes off CD, 2 minutes off pen drives), but the advantage afterwards is that there are no delays going back to the CD when starting applications. 2.3GB) which loads into tmpfs upon booting. Rather, Tin Hat is a massive image (approx. It does not mount any file system from CD via unionfs or otherwise. Tin Hat boots from CD, or optionally a pen drive, but it is not a LiveCD. Introduction Tin Hat is a Linux distribution derived from hardened Gentoo which aims to provide a very secure, stable and fast Desktop environment that lives purely in RAM. This makes for long boot times, but remarkable speeds during human-computer interaction. Rather, Tin Hat employs a massive squashfs image which expands into tmpfs upon booting. Tin Hat boots from CD, or optionally USB pen drive, but it is not a LiveCD in that it does not mount any file system from the boot device. It aims to provide a very secure, stable, and fast desktop environment that lives purely in RAM. Basile and Melissa Carlson Department of Information Technological, D’Youville College, Buffalo, New York 14201-1084 Abstract Tin Hat is a Linux distribution derived from hardened Gentoo.
