Secure De-Duplication using Convergent Keys (Convergent Cryptography) for Cloud Storage

One very important challenges of today’s cloud storage services is that the management of the ever-increasing amount of data. To create data management scalable, de-duplication has been a widely known technique to condense space for storing and transfer information measure in cloud storage. Rather than keeping multiple data copies with an equivalent content, de-duplication eliminates redundant data by keeping just one physical copy and referring different redundant data to it copy. Convergent Encryption, additionally called content hash keying, could be a cryptosystem that produces identical ciphertext from identical plaintext files. Data de-duplication could be a technique for eliminating duplicate copies of data, and has been wide employed in cloud storage to scale back space for storing and transfer information measure. Promising because it is, associate degree arising challenge is to perform secure de-duplication in cloud storage. Currently daily the foremost arising challenge is to perform secure de-duplication in cloud storage. Though Convergent Encryption has been extensively adopted for secure de-duplication, a essential issue of creating Convergent Encryption sensible is to with efficiency and dependably manage a large range of convergent keys. we have a
