Cloud Computing Security

Abstract

Advances in networking technology and an increase in the need for computing resources have prompted many organizations to outsource their storage and computing needs. This new economic and computing model is commonly referred to as cloud. While the benefits of using a public cloud infrastructure are clear, it introduces significant security and privacy risks. In fact, it seems that the biggest hurdle to the adoption of cloud storage (and cloud computing in general) is concern over the confidentiality and integrity of data. To address the concerns outlined above and increase the adoption of cloud storage, we argue for designing a virtual private storage service based on new cryptographic techniques. In this project work, the plain text of 128 bits is given as input to encryption block in whichencryption of data is made and the cipher text of 128 bits is throughout as output. The key length of 128bits, 192bits or 256bits is used in process of encryption.
