As most of the data transactions now-a-days are being made through secured smart cards owing to their low cost and ease of usage, it has become necessary to speed up the Key generation in the RSA algorithm [4]. Moreover, public key cryptography is a popular method that provides security, identification and authorization in secure transactions [5].The cryptography is classified into two types: Symmetric Key Systems and Asymmetric Key Systems. In Symmetric Key Systems same keys are used by the transmitter and receiver whereas in Asymmetric Key Systems different keys are used for encryption by the sender and decryption by the receiver. Hence these two aspects, namely speed of key generation at the same time maintaining the security are of prime importance and the major sources of motivation in carrying out the present work. During the study of the RSA algorithm, the following problems have been identified: a) the mathematical solutions of cryptographic algorithms require a large amount of calculation, which implies a higher consumption of computing resources and greater bandwidth for transaction; b) in order to store information in a database, for example four bytes, encrypted fields of approximately 600 bytes are required thus enhancing the space required c) increasing threats & vulnerabilities, due to the development of technologies [19, 20], result in the improvement of information security, which means higher cost and consumption of computational resources. This work proposes a generic model that optimizes the RSA method for information encryption, combining two different methodologies of key generation.This generic RSA model is expected to meet all the requirements and processes based on standard models accepted like cryptographic protocols and to make it suitable for transaction through smart devices like POS and other such transaction terminals.
