Data transmission through the internet applications is growing very fast, and this continuous growth demands for new network bandwidth and data security. Encryption plays a major role in security of information systems and internet based applications. In this study, the RSA algorithm was modified with bit-stuffing technique to improve the protection and security of confidential data while in transits or in storage. Our modified algorithm, RSA Bit-stuffed, was implemented and compared with the modified Ron Divest Code4 and the modified RSA in MATLAB using time complexity and avalanche effect as performance metrics. The experimental results showed that our augmented bit-insertion technique increased the time complexity against different attacks, boost the randomness of encrypted messages, and also improve security of encryption keys with bit-length lower than that of the standard RSA.
