Exponentiation in modular arithmetic
WebModular exponentiation ( Exponentiation Algorithms) is the main process in many of the cryptographic applications of this arithmetic. The notation is identical to that for integers and real numbers. {C}^ {D}\ (\textrm { mod N}) is D copies of C all multiplied together and reduced modulo N.
