Embedded Software Design of Scalable Low-Area Elliptic-Curve Cryptography

摘要

In this letter, a fully software implementation of scalable elliptic curve cryptography (ECC) over ${hbox{GF}}(2 ^{m})$ on a tiny microcontroller (PicoBlaze) is presented. The implementation performs the whole ECC point multiplication in only 0.257 s for ${m}=113~{hbox{bit}}$ , 0.405 s for ${m}=131~{hbox{bit}}$ , 0.75 s for ${m}=163~{hbox{bit}}$ and in 1.23 s for ${m}=193~{hbox{bit}}$ . 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.
