In this letter, a fully software implementation of scalable elliptic curve cryptography (ECC) over GF(2m) on a tiny microcontroller (PicoBlaze) is presented. The implementation performs the whole ECC point multiplication in only 0.257 s for m =113 bit , 0.405 s for m = 131 bit , 0.75 s for m = 163 bit and in 1.23 s for m = 193 bit . This design, either standalone or as part of a software-hardware codesign, opens up the potential of scalable public key cryptography to be used in secure resource constrained applications.
