Item Design and Implementation of Information Retrieval System for Laboratory Equipments(Journal of Mathematics Association of Nigeria, ABACUS, 2016) Oladipo, I. D.; Adewole, K. S.; Babatunde, A. O.; Abati, A. I.; Tomori, A. R.; Awotunde, J. B.Getting information relating to user's search criteria on equipment within a University laboratory has posed many challenges since there is no specific system to serve this purpose. It is difficult to handle the whole system manually. The aim of this paper is therefore to design and implement a web-based information retrieval system for University Laboratory equipment. This system offers a powerful internet-based search engine for locating and identifying equipment within a University laboratory while eliminating all unrelated content that a general-purpose search engine would retrieve. The method used involved collecting information needed from the technologist on various equipment in the laboratory and inserted into the retrieval system using SQL server to make query on the database to manage the data and a PHP programming language was used as the server-side scripting language for establishing an efficient querying of information from the database. Java scripting was also used as client-side scripting language for the purpose of adding more interactions to the proposed system. The developed system having been evaluated and assessed thoroughly was found to be efficient, easy to use for locating laboratory equipment in a University.Item A Network-based Key Exchange Cryptosystem Using Elgamal Algorithm(African Journal of Computing & ICT, 2014) Babatunde, A. O.; Adewole, K. S.; Abdulraheem, M.; Oniyide, S. A.A cryptosystem describes the system where two or more individuals communicate in a secret manner over a public channel. The contents of information shared on a public network need to be protected against unauthorized access using a more secured technique of encryption and decryption. A cipher is the heart of a cryptosystem, which specifies the policy for encryption and decryption. The encryption policy takes the plaintext and a predetermined key, and produces a ciphertext which hides the true meaning of the original plaintext. The decryption policy takes another key, which may be different from the encryption key, and recovers the plaintext from the ciphertext. In this paper, a cryptosystem is developed using Elgamal algorithm for key exchange purpose during information sharing on a public network. The proposed system provides a secure platform for encrypting and decrypting user's key. This key could be used by a symmetric algorithm for file encryption and decryption. The system is found capable of securing user's key from illegal access by an unauthorized person.
