Efficient Data Sharing In Cloud Medium with Key Aggregate Cryptosystem

In cloud storage the Resources are shared and, remotely accessed. And then we show how to securely, professionally, share data with others in cloud storage. And consider Aggregation is a collection of things to make retrieve a data but the key aggregate is a multiple keys produce a set of result in the cryptosystem. In the Advanced Key sharing system based on hint text methodology is formed to share the data safely.Once the data sharing is completed then the key aggregate differs from its actual form. So the user cannot guess the key aggregate cryptosystem and this process provides efficient solution than the existing ones.
