2. Montgomery modular multiplication - Wikipedia

   en.wikipedia.org/wiki/Montgomery_modular...

   Montgomery modular multiplication relies on a special representation of numbers called Montgomery form. The algorithm uses the Montgomery forms of a and b to efficiently compute the Montgomery form of ab mod N. The efficiency comes from avoiding expensive division operations. Classical modular multiplication reduces the double-width product ab ...

   The Mark 92 Fire Control System is a US-built medium-range anti-aircraft missile and gun fire control system. It was developed for the FFG-7 Oliver Hazard Perry class guided missile frigates. The system is a licensed USN version of the Thales Nederland WM-25 fire control system. The Mark 92 fire control system was approved for service use in 1975.

7. Modulo - Wikipedia

   en.wikipedia.org/wiki/Modulo

   The properties involving multiplication, division, and exponentiation generally require that a and n are integers. Identity: (a mod n) mod n = a mod n. nx mod n = 0 for all positive integer values of x. If p is a prime number which is not a divisor of b, then abp−1 mod p = a mod p, due to Fermat's little theorem.
