Data security protection in cloud computing by using encryption

الملخص EN

Cloud computing is a paradigm for offer information technology services on the Internet, such as hardware, software, networking and also the storage can be accessed anywhere at any time on a pay-per-use basis.

However, storing private data onto servers of the cloud is a challenging matter.

Therefore, cryptography technique and authentication are used in this model to ensure confidentiality and proper access control of sensitive data.

Therefore, in this paper I proposed a model to protect data in cloud computing.

In this model the algorithm of the RivestShamir- Adleman (RSA) is applied to the private data.

Furthermore, the protocol of Challenge-Handshake -Authentication-Protocol (CHAP) is used to improve the security of the authentication as well.

The results show this model is secure and practical
