Abstract:
Although smart cards have already provided secure portable storage device, security is still a major concern to electronic data systems against accidental or unlawful destruction or alteration during transmission or while in storage. One way of ensuring security is through encryption so that only the intended parties are able to read and access the confidential information. The software simulation result proved that the inclusion of the Odd-Even substitution to DES has provided additional confusion technique to DES and was essential in providing adequate security whilst having the stability and speed of handling encryption and decryption processes.
