Cloud computing is the delivery of computing service server, storage, databases, networking,
software, analytics, intelligence and more over the internet the cloud to offer raster innovation, flexible
resources and economics of scale. Software as a Service (SaaS) service is the top most layer of the cloud
computing stack directly consumed by end user i.e. SaaS. However, the new technology has also created new
challenges such as data security, data ownership and transcode data storage. Security is an important factor in
cloud computing insuring clients data is placed on the secure mode in the cloud. This paper describes about the
design and implementation of simplified algorithm based on data encryption standard (DES) algorithm. The
data to be encrypted is manipulated with the private key that is created.
Keywords: Algorithms: DES, Cloud Computing, SaaS Services.
