Over the past decade, the digital life of most people has moved from stationary devices such as desktop computers to computationally powerful mobile devices, such as smartphones, tablets or smartwatches. Not only do these devices bring a new level of convenience for users, they are also much more vulnerable to attacks that compromise the confidentiality of users' private data as revealed by whistleblower Edward Snowden's global surveillance disclosures.
One might think that similar attacks existed before, but mobile smart devices offer many new attack vectors that are not known from stationary desktop PCs. For example, a new class of attack vector results from the plethora of sensors these devices carry, such as GPS and motion sensors. Other attacks become possible because of the context switch between the mobile protocol stack and, e.g., Internet applications. While some of these attacks can be thwarted by sensible use of strong cryptography - for instance, there now exist secure text-messenger apps that allow users to encrypt their communication - strong cryptography alone is not able to protect against attacks that exploit side channels. Such side channels leak sensitive information about users and networks, and often are the stepping stone for severe follow-up attacks.
The research focus can be tuned to your interests. You will be expected to investigate different classes of attacks on networks and smart mobile devices. This requires the design and implementation of simulation models, but also the setup of large-scale measurement frameworks for real-world experiments. In a following step, you will process and analyse the collected data in order to draw conclusions. To investigate possible new attack vectors and defences against existing attacks, you will transfer and apply common methods from other research areas in order to find creative new solutions.
Fixed-term contract: you will be appointed for an initial period of 18 months, after which your performance will be evaluated. If the evaluation is positive, the contract will be extended by 2.5 years.
We want to get the best out of science, others and ourselves. Why? Because this is what the world around us desperately needs. Leading research and education make an indispensable contribution to a healthy, free world with equal opportunities for all. This is what unites the more than 22,000 students and 5,000 employees at Radboud University. And this requires even more talent, collaboration and lifelong learning. You have a part to play!
