ECC:<br />
Implementational choices<br />
• The choice of special curves can lead to<br />
substantial performance gains:<br />
• Subfield curves defined over GF(q)<br />
considered over GF(q n ):<br />
Use of Frobenius automorphism<br />
can speed up scalar multiplication.<br />
• Curves with special automorphisms:<br />
Similarly to the usage of the Frobenius,<br />
special automorphisms of a curve can considerably<br />
speed up the scalar multiplication.<br />
