Improving RSA Algorithm Using Multi-Threading Model for Outsourced Data Security in Cloud Storage
Purnima Gupta, Deepak Kumar Verma, Aswani Kumar Singh · 2018
Cloud Computing is a promising technology used by scientific and enterprise communities to access shared resources from anywhere through the internet. Users may also store their sensitive and confidential information on the cloud that requires an eminent encryption scheme and a fine-grained access policy to ensure privacy and security. Disparate obtainable symmetric, asymmetric and Attribute-Based Encryption has appreciable encryption schemes to keep secure the confidential data. In this paper, the authors have analyzed existing data encryption schemes, like RSA, KP-ABE, CP-ABE, and AES. The comparisons among them on the basis of computational cost and storage cost have been shown. Further, the authors have proposed an improving scheme to enhance the speed of RSA encryption using multi-threading concept on latest multi-core CPUs.
