Low-cost digital signature architecture suitable for radio frequency identification tags

The provision of effective security for RFID tags is essential for the uptake of this computing paradigm to be truly successful. Passive RFID tags are extremely resource constrained and therefore, it is very difficult to implement strong security on such devices. This paper illustrates for the first time that it is feasible to implement strong cryptographic techniques on low-cost passive RFID tags. Low-cost hardware architectures of a hash function and a digital signature, are presented, both of which are the smallest such designs proposed to date, and resulted from a collaborative research project on low-cost RFID architectures with Orange, (Cryptographer).
