Abstract -
Cloud computing technology is mostly used in many areas so that the data outsourced on cloud can accessed easily. In this paper, we show how to share data securely, efficiently, and flexibly with others in cloud storage. And we describe a new key aggregate cryptosystem [5], which produces a constant size cipher texts. The uniqueness of this scheme is that one can aggregate any group of secret keys and make them as compact as a single key, and the power of all the keys being aggregated. Once the data sharing is completed then the key aggregate differs from its actual form. So the users cannot guess the key aggregate cryptosystem and this provides efficient solution to existing systems.
