The discrete logarithm problem on E is to find the number k such that Q = kP. In this paper we reduce the discrete logarithm problem on E[n] to the discrete logarithm on the group F*_{q} , the multiplicative group of nonzero elements of Fq, in the case where n | q &minus 1, using generalized jacobian of E. }, URL = {http://ijmsi.ir/article-1-88-en.html}, eprint = {http://ijmsi.ir/article-1-88-en.pdf}, journal = {Iranian Journal of Mathematical Sciences and Informatics}, doi = {10.7508/ijmsi.2009.02.006}, year = {2009} }
