A note on high-integrity PC bootstrapping
نویسنده
چکیده
In this paper, we describe two techniques for assuring a high integrity startup in a PC based computing environment. We begin with background information on PC startup procedures and current integrity threats against normal PC startup. We then describe a sound technique for assuring a high integrity startup and the basis for its soundness. Next we show a second method which is not sound, but which works well against attacks not specifically directed against this defense.

A Secure and Reliable Bootstrap Architecture
In a computer system the integrity of lower layers is treated as axiomatic by higher layers Under the pre sumption that the hardware comprising the machine the lowest layer is valid integrity of a layer can be guaranteed if and only if the integrity of the lower layers is checked and transitions to higher layers occur only after integrity checks on them are complete The resulting integrity chai...

متن کاملFaster Bootstrapping of FHE over the Integers
Bootstrapping in fully homomorphic encryption (FHE) over the integers is a homomorphic evaluation of the squashed decryption function suggested by van Dijk et al. The typical approach for the bootstrapping is representing the decryption function as a binary circuit with a fixed message space. All bootstrapping methods in FHEs over the integers use this approach; however, these methods require t...

متن کاملMolecular basis for the immunosuppressive action of stearic acid on T cells.
Studies were performed to determine the mechanism by which stearic acid (18:0) selectively inhibits T-dependent immune responses in vitro. Incubation of mitogen-activated B and T cells with 18:0 resulted in dissimilar patterns of incorporation of the saturated fatty acid into their membranes. High-performance liquid chromatography (HPLC) analyses of T cells showed an accumulation of disaturated...
