NEW TECHNOLOGY FOR HARDENING READY-MADE TOOLS IN AQUAEOUS DISPERSED MEDIA

Q: Exploit Hardening Made Easy

Prior work has shown that return oriented programming (ROP) can be used to bypass W⊕X, a software defense that stops shellcode, by reusing instructions from large libraries such as libc. Modern operating systems have since enabled address randomization (ASLR), which randomizes the location of libc, making these techniques unusable in practice. However, modern ASLR implementations leave smaller ...

New Mathematical Tools for Quantum Technology

Progress in manufacturing technology has allowed us to probe the behavior of devices on a smaller and faster scale than ever before. With increasing miniaturization, quantum effects come to dominate the transport properties of these devices, between collisions, carriers undergo ballistic motion under the influence of local electric and magnetic fields. The often surprising properties of quantum...

Update on Q: Exploit Hardening Made Easy

After Q: Exploit Hardening Made Easy [2] appeared in Usenix Security 2011, we noticed a discrepancy in our results. Our experiments showed that we could create a ROP payload to call statically linked functions in 80% of programs larger than 20KB, and additionally dynamically linked functions in 80% of programs larger than 100KB. The only difference between the two experiments is that the latter...

Home Made: New Media in the Home Mode

This essay investigates the peculiar situation of a new media project which takes as its raw material the home-video archive of a deaf man gone blind. In an attempt to revive this 'lost archive', Planet Usher: An Interactive Home Movie looks to uncover enduring spaces of productivity and, in the process, to make a case for the enduring viability and importance of home modes of production. While...
