The development of autoimmune diabetes in the nonobese diabetic (NOD) mouse results from a breakdown in tolerance to pancreatic islet antigens. CD28-B7 and CD40 ligand-CD40 (CD40L-CD40) costimulatory pathways affect the development of disease and are promising therapeutic targets. Indeed, it was shown previously that diabetes fails to develop in NOD-B7-2-/-(More)
The HTTPS certificate ecosystem has been of great interest to the measurement and security communities. Without any ground truth, researchers have attempted to study this PKI from a variety of fragmented perspectives, including passively monitored networks, scans of the popular domains or the IPv4 address space, search engines such as Censys, and(More)

In this paper we explore the notion of a secure kiosk, a trusted computing platform built using off-the-shelf components. We demonstrate how kiosks serve as convenient primitives when designing secure computing protocols, as they allow for a very prescribed set of assumptions to be made about a system. We begin by defining the necessary properties of a(More)
