In this paper we propose Sancus, a security architecture for networked embedded devices. Sancus supports exten-sibility in the form of remote (even third-party) software installation on devices while maintaining strong security guarantees. More specifically, Sancus can remotely attest to a software provider that a specific software module is running(More)
The inclusion of third-party scripts in web pages is a common practice. A recent study has shown that more than half of the Alexa top 10000 sites include scripts from more than 5 different origins. However, such script inclusions carry risks, as the included scripts operate with the privileges of the including website. We propose JSand, a server-driven but(More)
—Typosquatting is the act of purposefully registering a domain name that is a mistype of a popular domain name. It is a concept that has been known and studied for over 15 years, yet still thoroughly practiced up until this day. While previous typosquatting studies have always taken a snapshot of the typosquatting landscape or base their longitudinal(More)
A fully abstract compiler prevents security features of the source language from being bypassed by an attacker operating at the target language level. Unfortunately, developing fully abstract compilers is very complex, and it is even more so when the target language is an untyped assembly language. To provide a fully abstract compiler that targets untyped(More)
Over the past decade, great progress has been made in the static modular verification of C code by means of separation logic-based program logics. However, the runtime guarantees offered by such verification are relatively limited when the verified modules are part of a whole program that also contains unverified modules. In particular, a memory safety(More)
Given the limited resources of wireless sensor network infrastructure , knowledge of the traffic generated by each node and service can be of great value. Yet, accounting and conveying this monitoring information in this low-resource infrastructure is challenging. Current monitoring solutions for wireless sensor networks either use passive monitoring,(More)
Consumer devices are increasingly being used to perform security and privacy critical tasks. The software used to perform these tasks is often vulnerable to attacks, due to bugs in the application itself or in included software libraries. Recent work proposes the isolation of security-sensitive parts of applications into protected modules, each of which can(More)
An important objective for low-level software security research is to develop techniques that make it harder to launch attacks that exploit implementation details of the system under attack. Baltopoulos and Gordon have summarized this as the principle of source-based reasoning for security: security properties of a software system should follow from review(More)
