A secure cryptographic cloud communication using DNA cryptographic technique

The main aim of the proposed work is to design a secure cloud storage and data distribution platform for the open cloud (public cloud). This platform offers the secure communication among client and server during the data transmission from the client device. In addition of that it also provides the secure technique to share and transfer the file from one user to another. Therefore to secure the entire communication and storage of cloud server a cryptographic cloud is proposed for implementation and design. To provide security using the cryptographic technique a number of traditional and modern cryptographic techniques are studied. In most of the cryptographic techniques either the time and space complexity is much higher or they are much frequently used and utilized from the classical security point of view. Thus in this presented work the DNA based cryptographic algorithm for security is used. The DNA based cryptographic technique is basically developed using the substitution and other basic operator's implementation. Thus this technique is less computational cost effective and efficient. On the other hand the only four symbols are used for transforming entire massage to the cipher. Due to this security is also enhanced in terms of their recovery process. The proposed SaaS (software as a service) demonstrate the security using the upload, download and sharing of files using the proposed platform. The implementation of the proposed security platform for data exchange and sharing is provided using the JAVA technology. Additionally for the deployment the OpenShift cloud (public cloud) is used. The experimental performance in terms of time and space complexity demonstrates the effective and low resource consuming technique for the cloud data security.
