Design and Implementation of Enhanced Secured Cloud Computing

M. Gayatri

Cloud computing plays a major role in providing different resources in the form of web services like tax calculation web service, e-banking web service etc., for smooth running of our daily lives. We can rely on cloud computing if these useful web services are really secure enough to use. This paper focuses on analyzing limitations of current cryptographic schemes used in providing security to data on cloud and highlights the usage of Elliptic Curve Cryptography scheme (ECC) used in cloud based applications and implements Elliptic curve digital signature algorithm on cloud data and compares its performance with RSA based scheme. The performance of elliptic curve cryptosystem heavily depends on an operation called point multiplication. In this paper a new point multiplication method using modified base representation is used. This method reduces the point addition as well as pint doubling operations thereby increasing the efficiency of computing time in performing encryption and decryption operations.
