How to Use Koblitz Curves on Small Devices?
[chapter]
2015
Lecture Notes in Computer Science
Koblitz curves allow very efficient scalar multiplications because point doublings can be traded for cheap Frobenius endomorphisms by representing the scalar as a τ -adic expansion. Typically elliptic curve cryptosystems, such as ECDSA, also require the scalar as an integer. This results in a need for conversions between integers and the τ -adic domain, which are costly and prevent from using Koblitz curves on very constrained devices, such as RFID tags or wireless sensors. In this paper, we
