Paper Title
Integration Of Encryption Of File And One Time Password For Secure File Accesson Cloud

Cloud computing is emerging technology which offer better performance and can be use to provide types of services such as Software as a Service (SAAS), Platform as a Service (PAAS) and Infrastructure as a Service (IAAS) at low cost. The issue in providing SAAS is security of cloud user’s data when it is uploaded on cloud and authentication of cloud user before accessing the data. To improve the security for the data retrieval from cloud environment, the client user has to use the One Time Password (OTP) provided by the cloud environment and provides data encryption which protects data from cloud vendor, an attacker. In this paper we are providing the OTP using MD5 and the encryption is done by using RSA. The One Time Password is sent to the user phone number to view the original data and help to share public data with other authenticated cloud user.
