Archived research projects in CRoCS laboratory

Below, you can find older projects, which are not currently actively pursued further, but may be activated again later (as happened for multiple projects already).

The first goal is research, and implementation of new algorithms (key derivation, authenticated encryption or integrity protection mechanism) into existing open-source LUKS/cryptsetup disk encryption project.

The second goal is to make LUKS/libcryptsetup (and supported FDE formats) truly multiplatform tool (Windows/Linux) with focus to independent and extensible open-source software based FDE (Full Disk Encryption) solution.

This project includes providing a secure platform that is transparent for applications in wireless sensor networks (WSN) - WSNProtectLayer. Our platform includes intrusion detection system (IDS) detecting active attacks. We consider privacy issues to prevent passive attacks on the WSN. We also propose secrecy amplification protocols and evaluate key management schemes. Current work includes parametrised attacker simulated on KMSforWSN framework.

This project focuses on usage, evaluation and extension of various tools related to secure programming, application vulnerabilities, security testing and code review. We are interested in static and dynamic analysis of applications with a special focus on security bugs, fuzzy testing, taint analysis and semi-automated review procedures and its incorporation into application development lifecycle. This project is coordinated with Y Soft Corporation, a.s., and for students participating in this project, there is a possibility to get a financial support from this company. More general information about Y Soft cooperation with students can be found here.

This project is focused on improving the implementation of standard empirical test of randomness since some complete tests (Linear Complexity, Spectral, Overlapping template matching) can take hours on standard computer for usual amount of data. Tests are usually grouped into test batteries (NIST STS, Diehard,TestU01) to provide more complex randomness analysis. Currently we are focusing on optimization of NIST STS battery.

Project description: This project focuses on automated generation of attacker's strategies against real implementation of various network applications. Currently, we aim to optimize existing Denial of Service attacks (DoS attacks, Link) in order to achieve maximum impact on the victim webserver. GANet contains source codes we are using - for now, combination of OS apps (Perfmon,…) and Python scripts.

Project description: We want to map the dark economy behind Denial-Of-Service attack services (DDoSaaS) for hire, the communication between DDoSaaS providers and customers and collect samples of attack traffic from real existing DDoS services. This project is about getting hands-on experience with network attacks in real environment instead of in closed labs, analyzing often neglected economy aspect of network attacks and dipping into the mindset of a cyber-criminal.

Project description: These activities look at the security issues of the Android installation files (APK). The Android APK files are digitally signed, but the signer can be anybody. Therefore it is possible to to modify the APK files (to include malware, for example) and resign it. This can be done in an automated way. Such a modification/infection can also be done online in the form of the man-in-the-middle attack where the APK package is transparently modified on its way from the server towards the mobile device if no encryption of the communication is done.
