AN ALGORITHM FOR COMPUTING A SEQUENCE OF RICHELOT ISOGENIES
2009
Bulletin of the Korean Mathematical Society
Preserved Fulltext
We show that computation of a sequence of Richelot isogenies from specified supersingular Jacobians of genus-2 curves over Fp can be executed in F p 2 or F p 4 . Based on this, we describe a practical algorithm for computing a Richelot isogeny sequence.
