Internet based transaction applications such as internet banking, online shopping etc involves sharing of very sensitive information between two or more parties that should be confidential. This requires very secure end-to-end connections that will ensure the data integrity, confidentiality, authenticity, etc. Cryptography is one of the most reliable and best, if not the best way to keep sensitive data from unauthorized users. This implies a good cryptosystem that maximizes security of the data/information been transferred and minimizes a substantial amount of delay time is needed. This is dependent on the particular cryptosystem one chooses to secure information. Also of the two known types of cryptosystems, the best in security is asymmetric cryptography, which uses two different keys; one for encryption and the other key for decryption, whiles symmetric cryptosystems use the same key for both encryption and decryption. The essential features of asymmetric cryptosystems that determines a cryptosystems efficiency and security are; encryption computation time, decryption computation time, performance, encryption throughput, decryption throughput, throughput, randomness, key length, Operation per Instruction (O/I).This research seeks to examine these properties of some asymmetric cryptosystems and subsequently develop a proposed one that is more secured and efficient. The results of this research clearly demonstrate that, the proposed cryptosystem has better results for all the properties stated above.
