Abstract

The evolution of the cloud computing furnishes a better way for the data storage. ABE with delegation is accustomed for accessing the data and keep it confidential. But this scheme faces some limitations like the cloud servers can replace the cipher text with some malignant intent. They may also cheat the eligible users as unauthorized ones. The cloud servers even face external threats like the security attacks. So, to protect against the security attacks and to preserve the data integrity in the cloud, a hybrid encryption with VD scheme is proposed by Xu et al. Even this scheme faces the challenges like having larger keys, more computational time and vulnerability to man-in-the-middle attacks. A secure Hybrid Encryption using ECC in clouds is proposed to overcome these problems. The application of Elliptic Curve Cryptography and its algorithms in the proposed work provides a greater security because of the Elliptic Curve Discrete Logarithm Problem. The proposed work ensures greater security with the aid of a smaller key size. It also ensures less computational time, less memory and communication bandwidth
