Secure Authentication in Cloud Computing using Diffie Hellman and One Time Password

Abstract

Cloud Computing is the delivery of various computing services on Internet. These services include data storage, servers, databases, networking, software and analytics. Although cloud computing is a boon to the Information technology, there are certain issues which needs to be tackled. The biggest issue is that of cloud security. The user data needs to be protected from unknown parties. Different types of encryption schemes and authentication techniques are used to tackle the issue of cloud security. The encryption schemes are- Homomorphic Encryption and Homogeneous Encryption. In this paper, we have used a symmetric key algorithm- Diffie Hellman along with One time password (OTP) for authentication which gives more security to the user data.
