Abstract: This work presents improving security of data communication system using advanced management of encryption software scheme. The work characterized a case study network designed with data encryption technique and then improved the network using an advanced data encryption technique. The encryption technique was developed using optimized blow fish algorithm which has the ability to segment keys and input packet matrix before simultaneous encryption. This process improves security, processing speed and time. The technique was implemented on Mathlab Simulink platform and tested. The result showed that the data encryption time of the new algorithm was 79.8ms against 113.05ms of the characterized system. The decryption key was improved from 8bit to 32bit in the new algorithm making the decryption process more complex for hackers, but improved data security in the system. Keywords: Encryption, Data communication, Fish algorithm, Decryption, Packet matrix.
I. INTRODUCTION Recently, Information and Communication Technology (ICT) has grown sporadically, no surprise considering the huge benefits it presents such as the limitless ability to send, receive, store and retrieve information in real time using the necessary hardware and software components. Today, this technology has been on the rise, due to the various effects that it has on enterprises, providing scalable infrastructures and global economic benefits, thus enabling exchange of various forms of data over networks (Afaf et al., 2016). According to Gurjeevan et al. (2016), this wireless network has provided a platform for various forms of communications, enabling business transactions, human resource management network, international public relations, mobile communication, internet services to mention a few. Due to this effect, various organizations, both top and small scale have adopted this process for communication, transmission, received and management of classified information via data network. However most of these networks lacks adequate security features and have become a target for hackers, hence there is need for adequate data network security (Tingyuan et al., 2019). In recent times, it was observed that computers and other devices connected to unsecured networks are highly vulnerable to external threats such as malware, ransom-ware and spyware attacks. A single attack can bring down the entire computer system of an organization and compromise personal classified information. There is need for precautionary measures to be adopted for adequate protection of shared data and data networks security is one of the best ways to do so. Data network security (DNS) refers to protective privacy measures that are employed for the prevention of unauthorized access to computer network, database and websites. It is very essential part of information and telecommunication organization of all forms (Dhanraj et al., 2015).
