Paper Title
A Secure Data Storage in Cloud using Lightweight Approaches
Abstract
Cloud computing is the platform that provides different services for the users and companies on a pay-as-you-use
basis. The security measure as far as the cloud storage concerned is low. Therefore the data compromise will occur due to
attacks by the third party users in cloud storage. To overcome the attacks in the cloud storage the lightweight approaches
such as fragmentation and replication mechanism are proposed. Using lightweight approaches the file that is uploaded and it
is split into fragments and replicate the fragmented data over the cloud nodes. In T-coloring fragmentation algorithm, each
node stores only a single file fragment of a particular data file, which ensures that no meaningful information is revealed on a
successful attack. Due to this the attacker cannot guess the locations of the fragmented file. In T-coloring replication
algorithm, the files can be replicated based on the various distance measures. The original content of the file can be obtained
by giving the request and downloading the file from the cloud storage. Due to this high level security is maintained in terms
of attack inside the cloud storage.
