An Survey Analysis of Security Issues in the Cloud Data Storage

In When it comes to meeting the key security needs of a cloud data centre, blowfish is used for the encryption of file slices since it is the quickest and has the maximum throughput when compared to other symmetric algorithms for encryption and decryption. It is the concept of splitting and merging that adds to the principle of data security. Because it is utilized in a cloud environment, the hybrid approach helps to make the distant server more secure, allowing cloud providers to acquire the trust of their customers. In terms of data security and privacy protection, the fundamental difficulty of distinguishing sensitive data from access control has been overcome. With the help of cryptography technology, original data can be converted into an unreadable format. Symmetric key cryptography and public key cryptography are the two types of encryption algorithms that are available. This method makes use of keyboard shortcuts to turn data into an unintelligible format. As a result, only those who have been granted access to the cloud server can access the data. The cypher text data is visible to everyone.
