[sage-support] A random point of jacobian group of HEC

2010-12-30 Thread Foad Khoshnam
Hi In order to completing my programming I need to have a random point of the jacobian group of a hyper elliptic curve. Is there any function in sage for my programming using? I know there exist a such function in magma ,but I don't have access to magma. Thanks -- -- To post to this group, send e

We discussed this briefly on #sage-devel a couple weeks ago, though the discussion died out and nobody got around to submitting a trac ticket about it (probably because it's not really clear which way to go on this...). Here's the log, which might answer some questions: http://sage.pastebin.com/EBq

Let "N=pq" be RSA modulus with public key "e". given an instance (x^e mod N, z mod N) where "z" an take value either (1+x)^2 or any random value, "r" belonging to Z_N, with probability 1/2, what can be the known best algorithm to distinguish (x^e mod N, (1+x)^2 mod N) from (x^e mod N, r) ? -- T
