Özet

This work presents a pseudo-random number generator for RFID tags. The proposed generator takes non-random seeds and produces output that passes popular randomness tests. The generator uses true random numbers extracted from a newly discovered property of the tag memories. Unlike previous work, the proposed scheme uses very little die area and clock, leaving space for other security applications as well. The scheme is inspired from a well founded pseudo random number generator, which has many variations for computer security applications. Even though it is simple and sequential, the proposed scheme's performance equals similar previous work, even though others depend on random number inputs. © 2013 Springer-Verlag London.
