**Abstract**

The security of data becomes more vulnerable despite the various safety measures. The significant contribution of the chapter is to describe the design of a secured Cloud storage mechanism using ECC. Many banks are using cloud technology. However, it is not free from hacks and threats. Here comes the focus on Cloud Security and a lot of research work is happening around it. ECC-based secured cloud framework with a logging mechanism provides a high-level design of the SSL VPN and secured cloud mobile banking. It helps to secure data transfer for users. Software applications and web services are handled by maintaining the log files securely, and this security scheme shields the aligning of different kinds of data elements to each provider using an ECC algorithm. It is implementing a two-layered security system, which includes both private and public cloud storage environments, also providing a customized secure logging mechanism that will be encrypted by ECC. The TRA (banking) customers will get lots of benefits from this cloud storage mechanism. The proposed design acts like a buffer for end users, Internet service providers, and Banks, so it is more effective and secure in the Cloud environment.
