WebMar 7, 2024 · If g is a primitive root modulo p k, then either g or g + p k (whichever one is odd) is a primitive root modulo 2 p k. [11] Finding primitive roots modulo p is also equivalent to finding the roots of the ( p − 1)st cyclotomic polynomial modulo p . WebNov 24, 2014 · If g is not a primitive root of p, g will only generate a subgroup of GF p.This has consequences for the security properties of the system: the security of the system will only be proportional to the order of g in GF p instead of proportional to the full order of GF p.. To take a small example: select p=13 and g=3.. The order of 3 in GF_13 is 3 (3^1=3, 3^2=9, … WebMar 9, 2011 · Given that g is a primitive root of 13, all the primitive roots are given by g k, where ( k, 12) = 1; so the primitive roots of 13 are g 1, g 5, g 7, and g 11. Then the product of all the primitive roots of 13 is congruent to g 1 + 5 + 7 + 11 = g 24 modulo 13. By Fermat's Theorem, g 24 = ( g 12) 2 ≡ 1 ( mod 13). omega learning center reviews
