Security and Privacy of Sensitive Data in Cloud Computing Using RSA

Abstract

Today's world internet is being used by almost everyone. Numerous file exchanges take place online including many official documents. These files require some sort of security mechanisms while being transmitted over the Internet. Technology has done a great deal for changing the way we live and do business today. In the fast-moving world we need something essential for fast computation. Along with the popular use of computer, Information security has also become one of the problems which need to be solved. Many security issues like the malware authors, information leakage, endangerment and unauthorized exploitation need to be taken into account. To control those issues, crypto-security is necessary. More Applications started to use Rivest–Shamir–Adleman (RSA). However, Since RSA on large blocks is computationally intensive and largely byte-parallel. System will parallel perform the encryption and decryption process in a distributed environment and the performance analysis shows improvement in terms of execution time and provides the security.
