Abstract: Technologies like cloud computing provide a generous storage service to outsource the business and personal data. The major research challenge of data outsourcing is ensuring data confidentiality. Public key cryptography (PKC) is used in an open networking environment like the internet, for secure communication without depending on a secure channel, even for key exchange. One of the common and well known PKC is RSA cryptosystem. In this paper, an improved secure RSA cryptosystem (ISRSAC) has been proposed to increase the complexity in factorising the value of modulus 'n'. In ISRSAC, due to the complexity of computation in 'n', it is computationally difficult to factorise and perform cryptanalysis. A comparison is done with RSA, MREA and ESRKGS cryptosystems to show that ISRSAC is efficient. The experimental results prove that ISRSAC consumes more time for cryptanalysis compared to ESRKGS, MREA and RSA cryptosystems and provides security for data outsourcing in the cloud.
