 The algorithm was originally developed by David G. Cantor (not to be confused with Georg Cantor), explaining the name of the algorithm.Cantor only looked at the case formula_323, the general case is due to Koblitz.The input is two reduced divisors formula_324 and formula_325 in their Mumford representation of the hyperelliptic curve formula_249 of genus formula_5 over the field formula_2.
