Security problems of systems of extremely weak devices

Klonowski M.

Annales Universitatis Mariae Curie-Skłodowska. Sectio AI, Informatica

2011

Vol. 11, no. 3

9--25

In this paper we discuss some fundamental security issues of distributed systems of weak devices. We briefly describe two extreme kinds of such systems - the sensor network and theRadio Frequency IDentification (RFID) system from the point of view of security mechanisms designer. We describe some most important particularities and issues (including unsolved problems) that have to be taken into account in security design and analysis. Finally we present some fundamental concepts and paradigms of research on security of weak devices. In the paper we also give a brief survey of ultra–light HB/HB+ - family of encryption schemes and so-called predistribution protocols.
