ABCRNG - Swarm Intelligence in Public key Cryptography for Random Number Generation

Cryptography is an important tool for protecting and securing data. In public key cryptography, the key generation plays a vital role for strengthening the security. The random numbers are the seed values in key generation process in many of the public key cryptography algorithms, such as Elgamal, Rivest_Shamir_Adleman (RSA) algorithm etc. Much effort is dedicated to develop efficient Random Number Generators (RNG) with good statistical properties. In addition, many optimized functions are available for generating random numbers. Various RNG are compared against the performance of intelligent optimization algorithms. As an outcome, Intelligent optimization algorithms are very efficient to solve complex problems and also helpful for generating random numbers. The primary objective of the proposed algorithm (Artificial Bee Colony Random Number Generator ABCRNG) is to provide quick and improved performance results having practical and feasible implementation of random number generators. To evaluate the randomness of the random numbers generated by ABCRNG, the Run test is carried out in up and down method and also in above and below mean method. Thus, pure random and non-repeating final keys are obtained by using ABCRNG which increases the key strength and security. The proposed ABCRNG can be used in many applications requiring random numbers and also in the design of secured public key cryptosystem.
