Cloud computing is a paradigm that gives user an efficient and scalable business model to perform various technology functions like network, hardware, storage, bandwidth, software etc. Services are provided by some other company and these can be accessed over internet therefore it is just an alias of using computer hardware and software beyond firewall. Benefits include unlimited storage, universal access, collaboration, scalability and revolutionizing the way modern computing works. But with benefits comes the problems like organizations are transferring data and applications over cloud but security remains a very important concern. There are many threats related to cloud security like data loss, data breaches, malicious attacks, privacy etc. In this article we have studied the current problems in cloud security and proposed a security model using encryption techniques like SHA and RSA to tackle such situations.
