3 results about "Discrete logarithm" patented technology

In the mathematics of the real numbers, the logarithm logb a is a number x such that b = a, for given numbers a and b. Analogously, in any group G, powers b can be defined for all integers k, and the discrete logarithm logb a is an integer k such that b = a. In number theory, the more commonly used term is index: we can write x = indᵣ a (mod m) (read the index of a to the base r modulo m) for r ≡ a (mod m) if r is a primitive root of m and gcd(a,m) = 1.
