Implementation Of Private Cloud Storage Based On WebDAV

The type of cloud computing includes public clouds, private clouds and hybrid clouds. Private clouds provide a secure business environment to the enterprise, so many companies are planning to implement private clouds. As a preferred platform for the deployment of web applications, widespread cloud computing has casused that an enormous number of application programs move to the clouds and many successful cloud service providers emerge. The storage management of the data center plays a vital role in cloud computing environments. With the growth of the business, an enterprise would like to employ private storage clouds, compared to public clouds. The private storage cloud exists as the opposite of the public storage cloud. Since a large amount of data are stored in the public clouds, more and more enterprises and governments hope to establish a secure internal data storage platform to further ensure security and to substitute the original solutions such as FTP, and to establish private clouds to store private data. In such private storage cloud, there are some new security issues. Firstly, how to distinguish the attackers from internal and those from external? Second, how to move secure intra-cloud data into an enterprise?In order to solve the safe problem of putting the confidential data or private data in public cloud, and more and more individuals and enterprises hope to replace conventional programs with new solutions in private clouds, this thesis puts forward a private cloud storage system (termed as AirDisk) based on the WebDAV protocol. Firstly, the system uses the Realtek scheme, chooses the RTL8196C chip as the main control chip, configures the Apache server on the OpenWrt. loads the WebDAV module to provide the user with a new solutions, in which the DAV module ensures the interaction security between the user and the system. Secondly, we choose the RTL8188RE as the wireless module to provide an AP-Client mode, which implements wireless relay for the Airdisk. Finally, in order to meet the flexibility of the equipment, we crossing compile and transplant the peanut shell client to the target board to implement dynamic domain name system (DDNS). AirDisk can be placed under the protection of a firewall at home or in an enterprise to guarantee that it is invulnerable to attack from the outside. Experimental results indicate that the system can meet the demands of home users and small office networks.
