Employing scrambled alpha-numeric randomization and RSA algorithm to ensure enhanced encryption in electronic medical records

Abstract

Diverse business sectors want to ensure that their data is secure and remains confidential. A major solution to the problem of data insecurity is the concept of cryptography. Various cryptographic algorithms have been developed over the years in order to ensure maximum level of message security during transmission over insecure mediums. There is no doubt that these algorithms have been able to remarkably curb the issue of data insecurity and reduce cyber-attacks. Both asymmetric cryptographic algorithms and symmetric cryptographic algorithms are secure. However for the purpose of this paper emphasis will be laid on asymmetric cryptography. Hence, this paper emphasizes on popular asymmetric algorithms like the RSA Cryptographic algorithm. In this paper we propose a secure means of data encryption and decryption by applying the concept of scrambled alpha-numeric randomization to provide a clear understanding of the operational mechanism of the RSA algorithm during the encryption and decryption process. The scrambled alpha-numeric randomization technique employs a unique numbering and or lettering sequence to every letter of the alphabet in the case of every new message receiver. This approach also implements the cryptographic message syntax as well as the use of American standard code for information interchange (ASCII) encoding. Furthermore, the understanding of this approach will encourage new ideas for further advancements and improvement of the existing RSA cryptographic algorithm. However, the major advantage will be to increase the security of data and ensure proper authentication of data.
