I maintain some computer scripts for computations relating to my research. These are for the GPL computer algebra system Pari/GP. You are welcome to download and use these scripts; both the scripts and Pari/GP itself are free. Please let me know if you encounter errors.
Tate Pairing Computation via Elliptic Nets [ Pari/GP ] - This implements the algorithms in my paper The Tate Pairing via Elliptic Nets.
Elliptic Divisibility Sequences Tools [ Pari/GP ] - These are general-purpose algorithms for experimenting with elliptic divisibility sequences over any field. Move between sequences and curves, generate terms efficiently, etc.
Elliptic Nets Tools [ Pari/GP ] - These are general-purpose algorithms for experimenting with rank two elliptic nets over any field. It requires the use of the Elliptic Divisibility Sequences Tools above.
