A Novel Unpredictable Temporal based Pseudo Random Number Generator

Random numbers are sequences of integers which show absolutely no relation to each other anywhere in the sequence. Pseudo random numbers (PRNs) are random numbers which can be generated deterministically. Pseudo random numbers are widely used in cryptographic protocols to provide secrecy. A wide variety of pseudo random number generators (PRNGs) were proposed earlier which exhibit characteristics of PRNG and generate pseudo random numbers. In this paper, we propose a temporal based algorithm to generate pseudo random numbers. Our algorithm utilizes dynamic system clock and product of two large prime numbers generated randomly. Using dynamic system clock, we ensure that the seed is obtained from entropy source of some physical phenomenon and product of large prime numbers generated randomly ensure randomness of generated numbers. Our algorithm is easy to implement on any computing device and can be used for generating sequence of pseudo random numbers for desired purpose.
