Location Privacy in Usage-Based Automotive Insurance: Attacks and Countermeasures

Intrusions into Privacy in Video Chat Environments: Attacks and Countermeasures

Video chat systems such as Chatroulette have become increasingly popular as a way to meet and converse one-onone via video and audio with other users online in an open and interactive manner. At the same time, security and privacy concerns inherent in such communication have been little explored. This paper presents one of the first investigations of the privacy threats found in such video chat...

Location Privacy against Traffic Analysis Attacks

We propose a method which provides location privacy against traffic analysis attacks. Traffic analysis is the process of intercepting and examining messages in order to deduce information from patterns in communication. It can be described as the passive attacks that try to deduce the traffic pattern based on the eavesdropped information. They launch an active attack according to the achieved i...

A survey on RPL attacks and their countermeasures

RPL (Routing Protocol for Low Power and Lossy Networks) has been designed for low power networks with high packet loss. Generally, devices with low processing power and limited memory are used in this type of network. IoT (Internet of Things) is a typical example of low power lossy networks. In this technology, objects are interconnected through a network consisted of low-power circuits. Exampl...

Combined Attacks and Countermeasures

Logical attacks on smart cards have been used for many years, but their attack potential is hindered by the processes used by issuers to verify the validity of code, in particular bytecode verification. More recently, the idea has emerged to combine logical attacks with a physical attack, in order to evade bytecode verification. We present practical work done recently on this topic, as well as ...
