1. Securing functional programs with floating-label information-flow control
Abstract : The work presented in this thesis focuses on information-flow control systems for functional programs, particularly on the LIO library in Haskell. The thesis considers threemain aspects in this area: timing covert channels, dynamic policies andenforcement mechanisms that improve precision of the analysis. READ MORE

2. Secure GNSS-based Positioning and Timing : Distance-Decreasing attacks, fault detection and exclusion, and attack detection with the help of opportunistic signals
Abstract : With trillions of devices connected in large scale systems in a wired or wireless manner, positioning and synchronization become vital. Global Navigation Satellite System (GNSS) is the first choice to provide global coverage for positioning and synchronization services. READ MORE

3. Towards Secure SIP Signalling Service for VoIP applications : Performance-related Attacks and Preventions
Abstract : Current Voice over IP (VoIP) services are regarded less secure than the traditional public switched telephone network (PSTN). This is due to the fact that VoIP services are frequently deployed in an relatively open environment so that VoIP infrastructures can be easily accessed by potential attackers. READ MORE

4. On Certificate Transparency Verification and Unlinkability of Websites Visited by Tor Users
Abstract : Certificate Transparency is an ecosystem of logs, monitors, and auditors that hold certificate authorities accountable while issuing certificates. We show how the amount of trust that TLS clients and domain owners need to place in Certificate Transparency can be reduced, both in the context of existing gradual deployments and the largely unexplored area of Tor.

5. Unwanted Traffic and Information Disclosure in VoIP Networks : Threats and Countermeasures
Abstract : The success of the Internet has brought significant changes to the telecommunication industry. One of the remarkable outcomes of this evolution is Voice over IP (VoIP), which enables realtime voice communications over packet switched networks for a lower cost than traditional public switched telephone networks (PSTN).
