Exploration Encryption Mechanism Using Single Key for Public Cloud Storage

Sharing of Data is an main functionality in cloud Computing. In this system, we show how to share data in
securely, flexibly, efficiently, and with others in cloud computing. Cloud storage is a bulk of information
online in cloud which is able to access from various and associated assets. Cloud storage can give great
openness and reputability, solid assurance, disaster recuperation, and most minimal expense. Cloud storage
having significant usefulness i.e. safety, productively, adaptable offering information to others. New public–
key encryption which is called as Enhanced Searchable cryptosystem (ESE) is presented. ESE produce
steady size ciphertexts such that effective authorization of decipherment rights for any arrangement of
ciphertext are conceivable. Any set of secrete keys can be aggregated and make them as single key, which
incorporates force of the considerable number of keys being aggregated. This aggregate key can be sent to
the others for decipherment of ciphertext set and remaining encoded records outside the set are stays secret.
