Abstract

This paper researches on cloud computing based-on authentication for the security verification using Elliptic Curve Digital Signature Algorithm (ECDSA). The study structure simply focuses on the communication interaction of the Cloud providing communities and a pictured Smartphone user. The Elliptic Curve Cryptosystem is envisioned as the basic framework for data transmission security in the paper that proffers solution. We reviewed various literatures on the elliptic curves and applied the cyclic elliptic curve group based-on finite field modulo q. With the theory established, we applied the Elliptic Curve Digital Signature Algorithm as developed by ElGamal to carry out some exemplified computational sequences. The detail of the computational algorithm was done in Mathematica as given by (Jouko, 2011) with no modifications except in its translational interpretation to fit into cloud computing security environment as maybe applied by the cloud providing communities to accelerate and meeting the needs of the users on-demand as a service with embedding security consideration. Our contribution to the cloud computing environment is brought about through computational experimental activities as exemplified in this field for interactive security awareness through digital signature authenticating mechanism.
