摘要：Cloud computing is collaboration of applications and services that run on a distributed environment using virtualized resources and accessed by common internet protocols and networking standards. Due to its feature and availability of its service at low cost it is achieving increased popularity in IT industry. But there are several issues in cloud computing such as security issues, network issues, performance issues, availability etc. which is ruining its growth. As, people store their confidential and private data on cloud, issues related to the security of their data is at the top. The user authentication is the key factors of security in cloud. Many of the organizations for authentication still relies on static password authentication technique, but this method is getting old and is becoming less secure. So, there is a requirement for a strong authentication technique. For implementing a strong authentication technique, this paper has proposed a dynamic one-time password technique with two factor authentication scheme in which mobile phones are used as an authentication device. This technique is very robust, secure, multi-factor, dynamic password based authentication scheme. In this technique, mobile phone will run a MIDlet which is responsible to produce one time password which is valid for short period of time. The produced one time password is then used by client to authenticate itself to the cloud. For securely transmitting all the information between client and server, secure socket layer (SSL) has been used. All the information is encrypted by AES-256 and sends over the network, along with that client can also use virtual private network for carrying the sensitive information into the cloud. So, this paper focus on the authentication and network issues of the cloud
