: Data security has become a major concern in the virtual world today .User authentication, data security and data maintenance are the major issues which needs to be handled thoroughly. Earlier authentication is done based on passwords, there after many algorithms came into existence for securing these passwords and data. With the emerging technologies and increase in computational power, algorithms are being broken easily. Recent algorithms like Rivest, Shamir, and Adelman (RSA) are getting diluted. To yield a high level security with smaller key sizes, this paper underlines a double authentication method using One Time Password (OTP) and Elliptic curve cryptography(ECC) encryption where ECC is used for both authentication and confidentiality.Maintaining large amounts of data on traditional servers requires high investments and maintenance costs due to which most of the data is being migrated from traditional servers to cloud storage services. The main objective of this paper is to handle security threats during authentication using ECC and deploy the entire application in cloud server.
