摘要：Cloud computing describes
highly scalable computing resources provided as an external service via the
internet. Economically, the main feature of cloud computing is that customers
only use what they need, and only pay for what they actually use. Resources are
available to be accessed from the cloud at any time, and from any location via
the internet. There’s no need to worry about how things are being maintained
behind the scenes—you simply purchase the IT service you require. This new,
web-based generation of computing utilizes remote servers for data storage and
management. One of the challenging issues tackled in the cloud computing is the
security of data stored in the service providers’ site. In this paper, we
propose a new architecture for secure data storage in such a way that users’ data
are encrypted and split into various cipher blocks and distributed among
different service providers site rather than solely depend on single provider
for data storage. This architecture ensures better reliability, availability,
scalability and security.
