Vývoj bezpečného nosiče klíčových dat, včetně bezpečného čtecího zařízení a aplikačního programového vybavení s prokazatelnou odolností proti kryptoanalytickým a dalším útokům

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.
