# primitive root of 17

number - primitive root of 17 . Also need help finding the volume please. A generator of (Z=p) is called a primitive root mod p. Example: Take p= 7. To brute force this, an attacker should expect to try all possible values of a (or b) between 1 and p-1 until he finds a value that yields A (or B). The first few for which primitive roots exist are 2, 3, 4, 5, 6, 7, 9, 10, 11, 13, 14, 17, 18, 19, 22,... (OEIS A033948), so the number of primitive root of … For such a prime modulus generator all primitive roots produce full cycles. Return -1 if n is a non-prime number. for each primitive nth root , n(x), the monic polynomial with integer coe cients of minimum degree with as a root. For example, if n = 14 then the elements of Z n are the congruence classes {1, 3, 5, 9, 11, 13}; there are φ(14) = 6 of them. If g is not a primitive root of p, g will only generate a subgroup of GFp. It is based on the (assumed) difficulty of calculating general discrete logarithms. Suppose is a natural number such that the multiplicative group modulo , i.e., the group , is a cyclic group. Primitive root of a prime number n is an integer r between[1, n-1] such that the values of r^x(mod n) where x is in range[0, n-2] are different.

The security of Diffie-Hellman is not based on the difficulty of factoring. Does it just increase the security? By the aforelinked definition of congruence classes, that means 2 is not a primitive rot of 17. 2 8 is congruent to 1 mod 17. Definition. crumunch beat me to the punch, but I'll add that saying "the" primitive root is very much the wrong way to think about it. Thus the powers of 2 from 1 to 16 won't form the desired complete reduced residue class. That is (3, 58) = (5, 58) … Given that shared keys can be created with apparently any combination of p and g, even ones that are not prime, I find this intriguing. To take a small example: select p=13 and g=3. It ensures that for every number 0 <= x < p, there is a distinct value of gx mod p. That is, it ensures that g can "generate" every value in the finite field. Join Yahoo Answers and get 100 points today. 10. (b) Show that 15 has no primitive root by calculating the orders of 2, 4, 7, 8, 11, 13, and 14 modulo 15. Thus, first find a small primitive root, i.e., find an a such that the smallest integer k that satisfies a k mod 13 = 1 is k = m – 1 = 12. 9.2 Primitive roots De nition 9.1. Here's another perspective of primitive roots: http://hi.baidu.com/phoebus08/blog/item/51a592edac... We'll stop once 1 appears the second time because then it's just going to repeat and not give any new congruence classes. (Geometry) The roots of unity form the vertices of a regular n-gon on … Elementary example. Given a prime number n, the task is to find its primitive root under modulo n. Primitive root of a prime number n is an integer r between[1, n-1] such that the values of r^x(mod n) where x is in range[0, n-2] are different. T(3,4)= Generator G's requirement to be a primitive root modulo p in the Diffie Hellman algorithm (2) Having searched, I've found myself confused by the use of P and G in the Diffie Hellman algorithm. The sum of their squares is 145? Examples: Given that 2 is a primitive root of 59, find 17 other primitive roots of 59. Following the usual steps of Diffie-Hellman, Alice and Bob should each select integers a, b between 1 and p-1 and calculate resp.
