User Confidentiality Protection in Cloud Computing Using Enhanced Elliptic Curve Cryptography (ECC) Algorithm

Abstract

Abstract— a lot of customers are concerned about their weakness to attack if their critical IT resources are beyond the firewall. The tremendously scalable nature of cloud computing allows users to access vast amounts of data and
use computing resources distributed across different interfaces. Cloud entities, such as cloud service providers, users and business partners, share the resources available at different levels of technological operations. This paper focuses on user confidentiality protection in cloud computing using enhanced elliptic curve cryptography (ECC) algorithm over Galois Field GF(2m). The Strength of the proposed ECC algorithm depends on the complexity of computing discrete logarithm in a large prime modulus, and the Galois Field allows mathematical operations to mix up data easily and effectively. The methodology used involves encrypting and decrypting data to ensure user confidentiality protection and security in the cloud. Results show that the performance of ECC over Galois Field, in two area of evaluation, was better than the ECC algorithm which is used for comparison purpose.
