Abstract: Data tracking and hacking is especially dangerous in modern defence forces where classified data transmission must envolve cryptographic methods for secure and reliable data coding. The more unpredictable the cipher is, the more reliable is the message. Hardware random number generator or true random number generator (TRNG) is crucial part for every telecommunication system that involves secure and confidential electronic data transfer (official state agencies, e-banking, military data networks…) because it generates random numbers from a physical process which provides statistically random noise signals, which are trully unpredictable contrary to pseudo-random number generators generated by various software algorithms. A typical hardware random noise generators employs transducer to convert random physical process (thermal noise, photoelectric effect or other quantum phenomena) to electrical signal, amplifiers and AD convertors. On the other hand, pseudo-random number generation based on methods and algorithms may be examined by statistical tests for randomnes and proove if it is cryptographically secure. We analyze the possibility to implement adsorption-based sensors noise for the creation of allgorithm for pseudo-random number generaton and also the possibility of adsorption-based hardware random generator.
