ABSTRACT In today’s complex digital world, the volumes of both structured and unstructured electronic data being shared between individuals and organizations continues to rise sharply as data theft and intrusion increases daily as Information transmission through internet may include sensitive personal data which may be intercepted. This research work is aimed at developing an information sharing software using RS cryptographic algorithm for data security and secure communication. The proposed system adopt structured system analysis and design methodology (SSADM), and implement using object oriented programming language PHP5 & MySQL data base for data storage and html 5 and css3 for the user interface. Therefore, high level of security has been provided using the proposed RS cryptographic technique which will generate encrypted key to every to every message sent to the recipient. The results shows that the proposed technique provides high information security and will enhance secure communication between the university of port Harcourt senate towards delivery of information to deferent units and department within the institution, However, if adequate data exchange mechanisms are in place, information theft could be at minimal. This research work could be beneficial the institution at large if adopted CHAPTER ONE INTRODUCTION 1.0 Introduction According to Demmy (1989) data security simply means the act of protecting something against attack, security is done as a result of safety. During the ancient times, record keeping was done by means of primitive notches cut into wooden stick, on bone fragments or marks pressed in clay tables. They soon improved with the development of papyrus and calamus pen. The ancient record keeping was well in hand and reached its peak in Roman Republic and Roman Empire. In this digital world of information transmission, information is the heart of computers, transmission and global economy transaction. In ensuring the security of data and information (confidentiality integrity, accuracy and authenticity) as characteristics of information, the concept of data and information hiding have attracted people to come up with creative solutions to protecting sensitive information from being intercepted or falling into wrong hands. Wireless Networks are becoming increasing widespread, and majority of coffee shops, airports, hotels, offices, universities and other public places are making use of these for a means of communication today K. R. Babu et al,(2010). They’re convenient due to their portability and high-speed information exchange in homes, offices and enterprises. The advancement in modern wireless technology has led users to switch to a wireless network as compared to a LAN based network connected using Ethernet cables. Unfortunately, they often aren’t secure and security issues have become a great concern. If someone is connected to a Wi-Fi network, and sends information through websites or mobile apps, it is easy for someone else to access this information S. A Laskar,etal,(1990).Wireless networks generate large amount of data, which often is sensitive and vulnerable to interceptions than wired networks. This has increased the risk for users significantly and to combat this consideration, wireless networks users may choose to utilize various encryption methodologies. Encryption is the key to keep information secure online in a Wi-Fi network V. Sundaram (2011). When information is encrypted, it’s scrambled into a code so others can’t get it. Thus, due to the high probability of information compromise associated with Wi-Fi networks, various encryption methods have been developed. However, commonly utilized encryption methods are known to have weaknesses and are susceptible to attacker’s thereby compromising confidentiality.in today’s era, everyone wants their necessary data to be handy, portable and accessible from almost every place they visit throughout the day and this is made possible by using wireless networks. Wireless networks as the name suggests, are those networks that are not connected by any physical means such as Ethernet cables and thus provide the user with great mobility and convenience. Also, it saves one from the expenses on the cables that would be required if wired network is chosen as well as makes it easier for moving the base of the devices from location to another by just moving the machine along with the wireless network card.A wired network helps in point to point transfer, that is, sends data between any two devices that are connected with each other through an Ethernet cable but in case of wireless networks, the transfer of data is a broadcast service where the data is sent to all possible directions in the medium within a limited range as the medium of data transfer is air here and not cables. Wireless networks consist of three basic components: Transmission of data using air waves, access points (AP) to establish a connection to the public or private (organization) network and the wireless client operated by the user. Wireless networks do not promise quality of service during transmission and chances of intrusion into such networks are very high since the transmission here takes place through the medium of air and not cables. So, it doesn’t only require protection against uninvited users from accessing the network but also needs to secure the users’ private data that is being transmitted.
