Research Areas: Electromagnetic Analysis, Electrical Engineering
After my Ph.D. in Electromagnetic Analysis from KU Leuven, Belgium in 2010, I came straight to Cryptography Research (CRI) in the States. The first and most famous paper in my research field has been written by CRI and as such it was a great opportunity for me to work here. I have always enjoyed figuring out how something works, picking it apart,
getting my hands on it. Many things in my home have been picked apart and wherever possible – everything is connected.
In our engineering team, we work to identify and develop new techniques for security analysis in order to make a thorough security assessment of our costumer’s products. That means we enter every customer product as a clean slate, we act as detectives and slowly but surely take the product apart as a backwards puzzle — we look for vulnerabilities, we test this, we test that, only to see how the product reacts. This gives us an indication of where and how the security can be improved. It is very important that we do our job thoroughly and that we find all vulnerabilities, big and small, because we want our costumer’s products to survive in the field.
In the CRI team we specialize in semiconductor security technologies. Our tamper- resistant ASIC designs have been successful in a range of high-threat environments and have an unparalleled security track record. Through our research we help solve many of the world’s most difficult data security problems.
With technology becoming more and more advanced and with functionality constantly increasing, it’s becoming harder for companies to understand the products they use and the security threats those products might pose. I really love what I do, we get to help big, exciting companies that are creating new products and building new markets.
