Secure Interface Design Leveraging Hardware/Software Support

Atri Bhattacharyya

Computer systems rely heavily on abstraction to manage the exponential growth of complexity across hardware and software. Due to practical considerations of compatibility between components of these complex systems across generations, developers have favou ...

SecureCells: A Secure Compartmentalized Architecture

Babak Falsafi, Mathias Josef Payer, Siddharth Gupta, Atri Bhattacharyya, Yuanlong Li, Florian Hofhammer, Andrés Sánchez Marín

Modern programs are monolithic, combining code of varied provenance without isolation, all the while running on network-connected devices. A vulnerability in any component may compromise code and data of all other components. Compartmentalization separates ...

Preventing Use-After-Free Attacks with Fast Forward Allocation

Sanidhya Kashyap

Memory-unsafe languages are widely used to implement critical systems like kernels and browsers, leading to thousands of memory safety issues every year. A use-after-free bug is a temporal memory error where the program accidentally visits a freed memory l ...

PoLPer: Process-Aware Restriction of Over-Privileged Setuid Calls in Legacy Applications

Mathias Josef Payer

setuid system calls enable critical functions such as user authentications and modular privileged components. Such operations must only be executed after careful validation. However, current systems do not perform rigorous checks, allowing exploitation of ...

Implementation of a Wireless Mesh Network of Ultra Light MAVs with Dynamic Routing

Dario Floreano, Bixio Rimoldi, Jean-Christophe Zufferey, Alberto Jimenez Pacheco

This paper describes the implementation and characterisation of a mobile ad-hoc network (MANET) of ultra-light intelligent flying robots. The flying nature of the network makes it suitable to collect or disseminate content in urban areas or challenging ter ...

Unifying software and hardware of multithreaded reconfigurable applications within operating system processes

Miljan Vuletic

Novel reconfigurable System-on-Chip (SoC) devices offer combining software with application-specific hardware accelerators to speed up applications. However, by mixing user software and user hardware, principal programming abstractions and system-software ...

A Portable Kernel Abstraction for Low-Overhead Ephemeral Mapping Management

Willy Zwaenepoel

Modern operating systems create ephemeral virtual-to-physical mappings for a variety of purposes, ranging from the implementation of interprocess communication to the implementation of process tracing and debugging. With succeeding generations of processor ...
