摘要：Cloud computing is becoming an attractive technology thanks to its diverse benefits such as: reducing costs, sharing computing resources, service flexibility, etc. However, the concept of data security and privacy has become a major issue. Indeed, the key challenge is to ensure users that the cloud service provider may store and process the raw data confidentially. The fear of seeing sensitive raw data stored and used are the major barrier to cloud services adoption. The use of methods capable of ensuring storage confidentiality and data processing located in cloud servers appears to be an effective way to overcome this barrier and to build confidence in cloud services. This paper describes a layered model of cloud security and privacy, and some approaches used for secure data in cloud environment. Specifically, we will focus on the encryption methods that can ensure data storage confidentiality and another technique that can ensure both data storage confidentiality and data treatments.
