Asokan works on the problem of understanding how to build "secure systems". The underlying thesis is that it is indeed possible to build systems that simultaneously satisfy three attributes: sufficiently secure, easy-to-use and inexpensive to deploy. The precise research question depends on the specific instance of the problem we look at. For example, in one recent research project (https://se-sy.org/projects/coco/) we explored the question of how to design a technique for two commodity devices to securely and reliably decide, without any user interaction, that they are in close physical proximity to each other. This is a relatively easy problem to solve this problem if we are willing to give up on one of the three attributes (security, usability or deployability). But meeting all three is harder. One approach is to make use of the fact that if two devices are co-present, they should "see" the same ambient environment using their sensors.
