Abstract

Cloud computing plays a major role in providing different resources in the form of web services like tax calculation, e-banking, etc. One can rely on cloud computing if these web services are really secure enough to use. This paper focuses on analyzing the limitations of current cryptographic schemes used in providing security to data on cloud, highlights the usage of Elliptic Curve Cryptography (ECC) scheme used in cloud-based applications, implements elliptic curve digital signature algorithm on cloud data, and compares its performance with RSA-based scheme (Rivest et al., 1978). 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 point doubling operations, thereby increasing the efficiency of computing time in performing encryption and decryption operations.
