A novel technique of cloud security based on hybrid encryption by Blowfish and MD5

摘要

The networks have moved worldwide and information has been considered in the digital form of bits and bytes. Critical information is stored, refined and sent in digital form on personal computers. Since information performs such an essential role, competition are purposing the personal computers for opening up communication programs to either swipe the hypersensitive information or even to agitate the critical information system. There is absolutely no differentiation of cloud aspect or client aspect encryption, so it diminishes the information security. To attain the goals of security system, the encryption algorithms must definitely provide enough power with high security put in place within an acceptable speed restriction. Therefore, the performance analysis becomes very important to the prevailing encryption algorithms. This paper proposes a novel parallel cryptographic algorithm, blending and changing from MD5 and Blowfish encryption schemes, which can upgrade security. A hybrid MD5-Blowfish cryptographic calculation is created to defeat the shortcoming from symmetric block cryptographic and hash function schemes.
