The main goal of the project is a research of security aspects of hardware implementations of cryptographic mechanisms. The implementations are called tamper-proof devices and they are typically smart cards or cryptographic coprocessors. The design of majority of available tamper-proof devices does not deal with various forms of side effects of cryptographic algorithms execution. A side-channel is the term commonly used for places where such undesirable information appears. The volume and usefulness of information we are able to extract depends on the form of the side-channel. However, number of scientific papers proves that it is possible to effectively analyse information from side-channels and use the results for compromise of tamper-proof devices.The project consists of three main areas. We will design and build laboratory instruments for implementation of attacks exploiting side-channels. The attacks will produce experimental data. The second area consists of a design of analytic methods for effective processing of experimental data in such a form that allows reconstruction of sensitive data. The proposed methods will be checked on real devices. The last area deals with the design of countermeasures against side-channel attacks. We will use already known approaches as well as the principles of our analytic methods. The goal is to decrease the amount of useful information in side-channels and determine minimum amount necessary for successful attack.
