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 ...

Multi-objective optimization of utility systems and heat exchanger networks: method and application to the solar assisted hydrothermal gasification case

François Maréchal, Alberto Mian, Adriano Viana Ensinas, Emanuele Martelli

This work presents a novel framework for the multi-objective synthesis of utility systems and Heat Exchanger Networks (HEN) under single or multi-period operations. In order to solve the resulting Mixed Integer Non Linear (MINLP) programming problem, a bi- ...

Improving systems software security through program analysis and instrumentation

Volodymyr Kuznetsov

Security and reliability bugs are prevalent in systems software. Systems code is often written in low-level languages like C/C++, which offer many benefits but also delegate memory management and type safety to programmers. This invites bugs that cause cra ...

Improving Scalability of Symbolic Execution for Software with Complex Environment Interfaces

Stefan Bucur

Manual software testing is laborious and prone to human error. Yet, among practitioners, it is the most popular method for quality assurance. Automating the test case generation promises better effectiveness, especially for exposing corner-case bugs. Symbo ...

Techniques for Identifying Elusive Corner-Case Bugs in Systems Software

Radu Banabic

Modern software is plagued by elusive corner-case bugs (e.g., security bugs). Because there are no scalable, automated ways of finding them, such bugs can remain hidden until software is deployed in production. This thesis proposes approaches to solve this ...

Multi-period analysis of heat integration measures in industrial clusters

François Maréchal, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener, Roman Hackl

TSA (total site analysis) has shown to be an efficient tool for identifying heat integration measures in industrial clusters, leading to the optimal design of utility systems and energy bill reduction. In order to justify investments, any proposed utility ...

ConfErr: A Tool for Assessing Resilience to Human Configuration Errors

George Candea, Lorenzo Keller

We present ConfErr, a tool for testing and quantifying the resilience of software systems to human-induced configuration errors. ConfErr uses human error models rooted in psychology and linguistics to generate realistic configuration mistakes; it then inje ...
