Hi John, hi Simon. For example i want to construct the Bose.Chowla sequence with parameters p=839 y h=17, my question is what way its better to construct this sequence?.
I want to know this because i'm researching on the Chor Rivest system. Thus I need a good algorithm to solve the DLP. 2014-05-04 9:34 GMT-05:00 Simon King <[email protected]>: > Hi Jan, hi John, > > On 2014-05-04, John Cremona <[email protected]> wrote: > > On 4 May 2014 13:20, Jan Medina <[email protected]> wrote: > >> I wan to calculate log(\theta+i,\theta) for i in a finte field and > theta a > >> primtive element > >> > > > > You can see the documentation of this function like this: > > > > sage: F=GF(101) > > sage: a=F(3) > > > > sage: a.log? > > > > and even the code using a.log?? > > I somehow have the impression that part of the problem is that John > thinks in terms of methods ( a.log() ), while Jan is thinking in terms > of functions ( log(a) ). > > Anyway, the documentation of the *function* "log" can be seen with > sage: log? > and the source code with > sage: log?? > > And it seems to be the case that ultimately the function call log(a) > will end up with the method call a.log(). So, answering Jan's question: > Yes, if alpha is is an element of a finite field with primitive element > theta, then log(alpha,theta) is essentially the same as directly calling > alpha.log(theta), and this the discrete logarithm. > > Best regards, > Simon > > > -- > You received this message because you are subscribed to a topic in the > Google Groups "sage-support" group. > To unsubscribe from this topic, visit > https://groups.google.com/d/topic/sage-support/mbx4_5AN208/unsubscribe. > To unsubscribe from this group and all its topics, send an email to > [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
