REVIEW ON:MULTIPLE DATA SHARING USING KEY AGGREGATE CRYPTOSYSTEM IN CLOUD STORAGE

As the development of new wireless technology is growing data sharing becomes a vital part in cloud storage. Sharing of data efficiently and in secured manner is of great importance. In this article, a cryptographic technique having secret keys can be aggregated to a compact single key by encompassing the power of all keys. This enables the secret key holder to release a fixed size aggregate key for any choices of cipher text set in cloud storage. A less secured smart card can be used to store the generated compact single key.
