Lockdown uberApp

Introduction

Lockdown provides the user with a red/green system: an isolated and constrained environment for performing online transactions, as well as a high-performance, general-purpose environment for all other (non-security-sensitive) applications. An external device verifies which environment is active and allows the user to securely learn which environment is active and to switch between them.

The original design and implementation of Lockdown is described in:

The implementation of Lockdown contained herein can be via the core build process (see Building uberXMHF (pc-legacy-x86_32)). Note that the implementation is a research prototype and does not yet fully provide the security properties of the design.
