Hi I'm a french student in Master of Mathematics, computers sciences and application to cryptology in Paris 7 university.
As part of my degree course, I have to understand and to describe the method of cryptanalysis of GSM encrypted communication. So I have some question about table parameters, I don't understand how we get the formula (1 - h*l^2 / Z)^k = (1 - c) What is the value of Z ? In the Excel sheet (http://reflextor.com/Rainbow.Tables.xls) we have Z = 2/N, but in the case where k=1 and c=50%, it contradict the matrix stopping rule of Hellman's matrix because we have h*l^2 = N/4 and not h*l^2=N. I would like to know if it's possible to have more precision about stopping rule in rainbow tables. (sorry for my bad english) _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
