Secure One Time Password OTP Generation for user Authentication in Cloud Environment

Cloud computing is one of today's most exciting technologies due to its ability to reduce cost associated with computing. This technology worldwide used to improve the business infrastructure and performance. The major threat that the cloud is facing now is security. So, the user authentication is very important step in cloud environment. The traditional authentication user name and static password or PIN code can be easily broken by the skillful attacker. An Unauthorized user can easily enter into the system if he knows the user credentials. Encryption algorithms play a main role in information security systems. Efficient password generation for user authentication is an important problem in secure Cloud communications. In the paper, the One Time Password OTP approach is used to authenticate the cloud users. The generated OPT is encrypted by RSA public key encryption to be more secure for the cloud user authentication. So the third party is not required to generate OPT in the proposed paper. This paper can help to solve the user authentication problem in Cloud environment.
