A Survey on Asymmetric Key Aggregate Encryption in Data Sharing
Shilpashree P | Dr. K. N. Narasimha Murthy 
Abstract: Data sharing is the ability to share the same data resource with multiple applications or users. The data can be shared with others in a secure, efficient and economic way. Internet and cloud storages are rapidly growing day by day. So sharing of sensitive data through internet and cloud storage is an issue because there is a possibility of third party can steal the sensitive and confidential data. To overcome this problem data should be encrypted before sent across internet. Encryption is a technique of converting plaintext to ciphertext. Asymmetric is a kind of encryption which helps to share a data in a public key encryption, here the encryption key and decryption key are different. In this paper, the concept of aggregator key is introduced, which collects all the keys generated by the data owner and made it as a compact key. This compact key has consists of number of keys and using this aggregate key the data consumer can access only the data who is authenticate.
