### Paper: A note on L\'opez-Dahab coordinates

Authors: Tanja Lange URL: http://eprint.iacr.org/2004/323 Search ePrint Search Google L\'opez-Dahab coordinates are usually the system of choice for implementations of elliptic curves over binary fields. We give new formulas for doubling which need one squaring less and one more addition. This leads to a speed-up for binary fields in polynomial basis representation.
