Efficient ECC implementation architecture suitable for RFID technology.

In this paper, we provide an investigation on the feasibility of embedding the ECC authentication service in RFID chip-set. Thus, we deal with the implementation of the most costly operation, which is the scalar point multiplication. It is also considered as the core of the security of the ECC protocols. Two architectures are studied and implemented using the Montgomery algorithm adopting the affine and projective coordinates. According to the obtained results, we show that the scalar point multiplication implementation using affine coordinates is efficient in terms of speed and area than the projective coordinates architecture.
