Confronts and Issues of Cloud Security

Cloud computing was an Internet based computing, where shared resources, software and information, are presented to computer and devices. This paper shows the cloud security, privacy and reliability when a third party processing sensitive data. Security is one of the main challenges that hinder the growth of cloud computing. We have also explained cloud computing strengths, weaknesses, and applicable areas in information risk management. A new encryption based on Attribute Based Encryption using as a function, digital signature and asymmetric encryption schemes has been proposed. Our proposed algorithm is simplified as an efficient algorithm to implement cloud critical application.
