As the number of people being connected to online communication system through their mobile phone, computer or any other e-communication tools increases, there is need to secure the communication networks from adversaries (third parties) between the sender and receivers. There are many aspects to security approach in online communication environment. One essential aspect for secure communications is that of cryptography, which is the focus of this research. This research work aims at designing and implementing cryptosystem using a simple polyalphabetic cipher algorithm. The algorithm was coded with Java programming language. It was discovered that cryptography system with polyalphabetic cipher algorithm is better compared to Atbash cipher, Scytale cipher, Ceasar cipher etc, because it is very difficult for adversaries to decrypt an encrypted data without the key.

As Global System for Mobile (GSM) software is relatively new in the market and the level of awareness of its quality service is low; the need for quality assessment of these services cannot be overemphasised. We have estimated the distribution of time interval between failures variable to follow a Poisson process with the parameter, λ. The intervals between failures follow an exponential distribution and from this, we estimated the reliability of the software indirectly the quality service of Funtone. Furthermore, we carried out a Monte Carlo simulation; the result is in total agreement with what has been predicted by Poisson and exponential distributions. .
