Today, the cloud computing became most popular and the number of users is increases day-by-day, these increases malicious, unauthorized data access and we need to employ secure accessing mechanisms using cryptographic techniques. Here, we use attribute-based mechanism to provide decryption keys to the users based on access policies provided by the owners and secure data distribution using proxy re-encryption.

Cloud computing, Identity based encryption, Attribute based mechanism, proxy re-encryption, cryptographic techniques.
