Disk encryption without passwords

Disk encryption is essential for physical computer security, but seldom used due to the trouble of remembering and typing a password at every restart. We describe Mandos, a program which solves this problem, its security model, and the underlying concepts of its design.

Any security system must have a clear view of its intended threat model – i.e. what threats it is actually intended to protect against; the specific choices and tradeoffs made for Mandos will be explained. Another danger of security system design is the risk of its non-use; i.e. that the system will not be used for some real or perceived drawbacks, such as complexity. The deliberate design choices of Mandos, involving low-interaction, “invisible” and automatic features, will be covered.
