2012-06-11 04:55:47 +0200 | asked a question | Accessing functions inside .gp files I am newbie thus please forgive me if my request is trivial! I want to read a
file of gp extension. And in that file, I have functions. How could call these
functions when I want to use it? When, I try the above code in a terminal, it works fine. But when I try it in
sage notebook(), it works till line 8. And when it reaches 9, it says Traceback (click to the left of this block for traceback) |

2012-06-02 09:05:35 +0200 | asked a question | loading satoh-fgh in sage Does any body know how to use satoh-fgh.gp(point counting algorithm) for characteristic 2 elliptic curves in SAGE? |
2012-06-01 05:19:39 +0200 | asked a question | Order of randomly generated elliptic curve I was computing order of random elliptic curves over prime field with out any problem. But when it comes to computing order of elliptic curves over binary field(characteristic 2 field), it computes well for small values of a and b of the elliptic curve. The problem comes when a and b parameters are large, specifically for 163 bit elliptic curve parameters. I can generate random point of the elliptic curve of 163 bits. However, when I compute its order, it displays exhaust memory and then it exits and some times Jim dead message is displayed. I could not understand the problem. Could you say something for me regarding this problem? Thank you in advance. |

2012-05-03 07:41:06 +0200 | answered a question | NIST B-283 Elliptic Curve Please, help to compute order of the above elliptic curve E using SAGE and libraries in sage? |
2012-04-26 10:21:22 +0200 | answered a question | NIST B-283 Elliptic Curve I want to know the order of the curve that have been built above i.e K283_curve.order(). Is there a way to know the order of that curve and in that how could I generate a random point which is element of that curve? this works fine FF = sage.rings.finite_rings.finite_field_ext_pari.FiniteField_ext_pari;K. = FF(order, 'a', modulus=x^283 + x^12 + x^7 + x^5 + 1 )[] How could I get its order? In that, how could I find a random point of that curve? |
2012-04-24 11:15:06 +0200 | asked a question | computing order of elliptic curves over binary field Do you have any information on how to compute order of elliptic curves over binary field in SAGE mathematics software? Example: I have the following domain parameters which are taken from The problem I am facing is to to know the order of this elliptic curve? I ahve got on the net that it is possible to compute using this library sage.rings.finite_rings.finite_field_ext_pari.FiniteField_ext_pari and it takes these parameters properly with out any error. But there is error while requesting the order of that parameter. This was what I deed in sage: |
