Abstract
A cryptographic process receives initialization material and generates an output. The cryptographic process comprises the incrementing of a counter. The process of incrementing of the counter comprises incrementing the value of the counter cyclically through a loop of values, one value at a time. The values in the loop of values are chosen in accordance with a modified remainder number system comprising at least two remainders. Each of the at least two remainders is assigned a modulus of a fixed period. The period of at least one modulus of n-bits is selected by the equation period = floor (2n/p) *p where p is a prime number and floor (2n/p) > 1. The output of the counter is utilized in the course of generating the output of the cryptographic process
