Design and Implementation of a Yoruba Language Crytosystem

Abstract

Security has always been a bedrock for transaction and protection of human lives and until the existence of artificial intelligence, humans have learned to trust themselves for each other safety or safety of information except for few times where security was threatened by breach of trust or betrayal by persons which often led to enormous crisis. Recent research works have been able to achieve some high level of success in security of information. However, communication in Yoruba language using the Yoruba alphabet and symbols is still at its infancy. In other to achieve acceptable quality of information security of Yoruba alphabet and symbols in text, there is need for a robust security system. There are multiple layers of security, requirements and features which need automated technicality for assurance of effective security. In this paper, encryption and decryption of information written in Yoruba as text is  achieved using Caesar Cipher Algorithm to carry the Yoruba people along in the advancement taking place in the world of information technology. It adopted a symmetric encryption algorithm that uses one key for both encryption and decryption and used digits as its ciphertext which is a novel means of ensuring difficulty in breaking the codes as patterns with digits are not easily recognizable.
