Sebastian Lindner 2020
This repository contains magma, python and bash files related to explicit formulas
for ramified and balanced divisor split genus 2 and 3 arithmetic, polynomial
arithmetic for generic genus arithmetic, and testing scripts.
-------------------------
Genus 2 and 3 Formulas:
-------------------------
Testing files included are:
test_all.sh
- A shell script that runs all tests for explicit balanced
split and ramified genus 2 arithmetic.
- Invokes: posReduced/arb_splitG2_whiteBox_tester.mag,
posReduced/arb_splitG2_random.mag,
posReduced/ch2_splitG2_whiteBox_tester.mag,
posReduced/ch2_splitG2_random.mag,
posReduced/nch2_splitG2_whiteBox_tester.mag and,
posReduced/nch2_splitG2_random.mag,
negReduced/arb_splitG2_whiteBox_tester.mag,
negReduced/arb_splitG2_random.mag,
negReduced/ch2_splitG2_whiteBox_tester.mag,
negReduced/ch2_splitG2_random.mag,
negReduced/nch2_splitG2_whiteBox_tester.mag and,
negReduced/nch2_splitG2_random.mag in g2/splitModel folder.
arb_ramifiedG2_whiteBox_tester.mag,
arb_ramifiedG2_random.mag,
ch2_ramifiedG2_whiteBox_tester.mag,
ch2_ramifiedG2_random.mag,
nch2_ramifiedG2_whiteBox_tester.mag,
nch2_ramifiedG2_random.mag in g2/ramifiedModel folder.
negReduced/arb_splitG3_whiteBox_tester.mag,
negReduced/arb_splitG3_random.mag,
negReduced/ch2_splitG3_whiteBox_tester.mag,
negReduced/ch2_splitG3_random.mag,
negReduced/nch2_splitG3_whiteBox_tester.mag and,
negReduced/nch2_splitG3_random.mag in g3/splitModel folder.
- The test_all.sh script can be run by typing:
'./test_all.sh'
*_whiteBox_tester.mag
- White box testers cover all possible computation path in the
explicit formulas by computing one divisor composition
computer generated for each possible computation path.
*_random.mag
- Random testers compute 2500-5000 random divisor additions and
doubles using explicit formulas over randomly chosen small
characteristic fields for each arb, ch2 and nch2 settings.
Genus 2 formulas are located in the g2Formula sub folders of g2/ramifiedModel,
g2/splitModel/posReduced and g2/splitModel/negReduced, genus 3 formulas are located
in g3/splitModel/negReduced/g3Formula.
