Secure Implementations of Lightweight Cryptographic Algorithms
Description of research
We increasingly rely on embedded systems in our everyday lives; examples are smart cards, RFID tags, and sensor nodes that are used for public transport, health care monitoring equipment, pay TV systems, smart electricity meters, anticounterfeiting, electronic road pricing, etc. Ensuring the security and privacy requirements of these systems is a growing problem, and security by obscurity still prevails in this context, as witnessed by the breaking of the cryptosystems used in GSM mobile phones, KeeLoq car keys, and RIFD cards such as Mifare Classic, the Dutch “OV-chipkaart” and the London Underground Oyster card.
One central challenge in embedded security is that because of resource constraints (e.g. in computation power, circuit size, and cost) standard cryptographic algorithms cannot be used. Another challenge is that because attackers can get physical access to the devices, (hardware) implementations of these algorithms need to resist side-channel attacks, the most potent class of attacks on cryptographic algorithms.
Moreover, any countermeasures to side-channel attacks must be lightweight, given the resource constraints.
The goal of this PhD study will be to develop a deeper understanding of side-channel analysis and countermeasures. In particular, of special interest are lightweight countermeasures that can be applied to symmetric primitives hindering all known side-channel attacks. We will use the results from the side-channel analysis to design symmetric cryptographic primitives that allow flexible parametrization to meet the constraints of the device.
