Latency Interfaces for Systems Code

Rishabh Ramesh Iyer

This thesis demonstrates that it is feasible for systems code to expose a latency interface that describes its latency and related side effects for all inputs, just like the code's semantic interface describes its functionality and related side effects. S ...

A RISC-V Extension to Minimize Privileges of Enclave Runtimes

Edouard Bugnion, Neelu Shivprakash Kalani

In confidential computing, the view of the system software is Manichean: the host operating system is untrusted and the TEE runtime system is fully trusted. However, the runtime system is often as complex as a full operating system, and thus is not free fr ...

A Deep-Learning Approach to Side-Channel Based CPU Disassembly at Design Time

Mirjana Stojilovic

Side-channel CPU disassembly is a side-channel attack that allows an adversary to recover instructions executed by a processor. Not only does such an attack compromise code confidentiality, it can also reveal critical information on the system’s internals. ...

MINERVA: Browser API Fuzzing with Dynamic Mod-Ref Analysis

Mathias Josef Payer

Browser APIs are essential to the modern web experience. Due to their large number and complexity, they vastly expand the attack surface of browsers. To detect vulnerabilities in these APIs, fuzzers generate test cases with a large amount of random API inv ...

Distributed Momentum for Byzantine-resilient Stochastic Gradient Descent

Rachid Guerraoui, El Mahdi El Mhamdi, Sébastien Louis Alexandre Rouault

Byzantine-resilient Stochastic Gradient Descent (SGD) aims at shielding model training from Byzantine faults, be they ill-labeled training datapoints, exploited software/hardware vulnerabilities, or malicious worker nodes in a distributed setting. Two rece ...

LIGHTBLUE: Automatic Profile-Aware Debloating of Bluetooth Stacks

Mathias Josef Payer, Daniele Antonioli

The Bluetooth standard is ubiquitously supported by computers, smartphones, and IoT devices. Due to its complexity, implementations require large codebases, which are prone to security vulnerabilities, such as the recently discovered BlueBorne and BadBluet ...

FuzzGen: Automatic Fuzzer Generation

Mathias Josef Payer

Fuzzing is a testing technique to discover unknown vulnerabilities in software. When applying fuzzing to libraries, the core idea of supplying random input remains unchanged, yet it is non-trivial to achieve good code coverage. Libraries cannot run as stan ...

Security Vulnerabilities of the Cisco IOS Implementation of the MPLS Transport Profile

Jean-Yves Le Boudec, Miroslav Popovic, Teklemariam Tsegay Tesfay, Sergio Barreto Andrade

We are interested in the security of the MPLS Transport Profile (MPLS-TP), in the context of smart-grid communication networks. The security guidelines of the MPLS-TP standards are written in a complex and indirect way, which led us to pose as hypothesis t ...

Automated Vulnerability Discovery in Distributed Systems

Rachid Guerraoui, George Candea, Radu Banabic

In this paper we present a technique for automatically assessing the amount of damage a small number of participant nodes can inﬂict on the overall performance of a large distributed system. We propose a feedback-driven tool that synthesizes malicious node ...

Execution Synthesis: A Technique for Automated Software Debugging

George Candea, Cristian Zamfir

Debugging real systems is hard, requires deep knowledge of the code, and is time-consuming. Bug reports rarely provide sufficient information, thus forcing developers to turn into detectives searching for an explanation of how the program could have arrive ...
