Chaining Layered Integrity Checks - Arbaugh (1999)   (3 citations)  (Correct)

....the operating system is started. The Birlix model, unfortunately, does not validate the integrity of any of the lower level firmware, expansion ROMs or boot blocks. As a result, it leaves itself open to exactly the types of problems Birlix was attempting to prevent. 22 3.1. 3 BITS Clark [Cla94] CH94] presents a secure boot process (BITS) for DOS that utilizes an 8 bit expansion board, a smart card drive mounted in a floppy bay, software for configuration, software for file verification, and finally a smart card. BITS stores some of the OS bootstrap code on the smart card as well as ....

....a flaw or some trapdoor that can be exploited. The goal of AEGIS is to prevent tampering of components that are considered trusted by the system administrator. The nature of this trust is outside the scope of AEGIS. Other work on the subject of secure system bootstrapping includes [TY91, Yee94, Cla94, LAB92] A more extensive review of AEGIS and its differences with the above systems can be found in [AFS97] 4.2 Cryptographic Primitives SANE provides access to various cryptographic primitives. These can be used by other applications as is or as building blocks for more complex protocols. ....
