Study and improved data storage in cloud computing using cryptography

Abstract

Cloud computing is becoming a powerful network architecture to perform computing that is both large and complex. We present a cloud computing survey which outlines its core concepts, architectural principles, state-of-the art deployment and research challenges. Due to security issues, information over the Internet is becoming important. We have suggested a method to protect critical file data. Cryptography algorithms are an efficient way to encrypt sensitive data. It is a retrieval and transmission system that is readable only by intended users. The low cost and data usability of cloud computing is advantageous. Cloud storage has many advantages at low cost and data connectivity through the Internet. Ensured cloud data protection is an important part of the cloud computing environment because customers often store sensitive information with cloud storage services but they are not secure services. So, it remains a challenge to exchange data in a safe way while storing data from an unconfident cloud. Our solution guarantees consumer confidential data protection and privacy by using the AES, RC2 algorithm to store data in a single cloud. The cloud computing concept and transitional discussion under cloud computing will be provided previously proposed. The cryptographic algorithm used in cloud is then addressed and the latest trend for cloud security
