“…They have proposed and compared two genetic-based OTP key generators, namely, 10P-GRKG and the GRKG. The comparison results in [3] show that the GRKG method is much better than the 10P-GRKG method in terms of speed and randomness. However, it is observed that the GRKG method has certain limitations which needs improvements.…”

“…This motivates us to utilize (genotype) genetic algorithms in development of deterministic scheme that can generate the OTP keys rapidly. In 2013, Sokouti et al [3] have demonstrated a significant use of genetic algorithm for automatically generating OTP keys. They have proposed and compared two genetic-based OTP key generators, namely, 10P-GRKG and the GRKG.…”

“…As compared to GRKG, the proposed IGRKG generator generates the OTP key rapidly and the degree of randomness of the generated keys is better. In the literature, a prior attempt in OTP key generation using evolutionary technique has been addressed only in [3]. Therefore, this paper can present a detailed comparison between GRKG and IGRKG generators.…”

“…However, it is not trivial to generate pseudorandom key equal to the length of the plaintext. In this context, Sokouti et al (2013) [3] have proposed the GRKG method. GRKG generator accepts a fixed size short secret key as an initial key and thereby generates the pseudorandom key .…”

Recently, a genetic-based random key generator (GRKG) for the one-time pad (OTP) cryptosystem has been proposed in the literature which has certain limitations. In this paper, two main characteristics (speed and randomness) of the GRKG method are significantly improved by presenting the IGRKG method (improved genetic-based random key generator method). The proposed IGRKG method generates an initial pad by using linear congruential generator (LCG) and improves the randomness of the initial pad using genetic algorithm. There are three reasons behind the use of LCG: it is easy to implement, it can run efficiently on computer hardware, and it has good statistical properties. The experimental results show the superiority of the IGRKG over GRKG in terms of speed and randomness. Hereby we would like to mention that no prior experimental work has been presented in the literature which is directly related to the OTP key generation using evolutionary algorithms. Therefore, this work can be considered as a guideline for future research.
