The introduction of public-key cryptography is an important watershed in the history of cryptography. The work sparked off interest in the cryptographic research community and soon several public-key schemes were proposed and implemented. This abstract model is the most widely used public-key scheme today. However, increased processing power and availability of cheaper processing technology occasioned by the exponential growth in digital technology has generated some security concerns, necessitating the review of security parameters for enhanced security.
