Abstract—Cloud computing, is network based model used to
illustrate a variety of computing concepts that involves a large
number of computers connected through a synchronized
communicational network such as the Internet. Cloud users
demands security to their data which are stored in data
repositories of cloud service provider. Thus the concept of
Network Security can be applied over the cloud network, where
several encryption algorithms are applied to provide integrity
on the data. Such algorithms include Symmetric encryptions,
Asymmetric encryptions, Hashing algorithms and Digital
signatures. Even though these algorithms provide security,
however these are not applied on query based data retrieval
from databases where certain queries are used to invoke the
data. Till to date many researchers proposed several models to
provide security to the data in database and are not upto the
mark. Since the operations are done in database which is
located remotely, away from user, providing encryption on
queries and data together will make an efficient approach. Such
mechanisms like Homomorphic encryption, Order-preserving
encryption are examined and a novel approach is defined to
meet all security issues over a cloud termed as “CryptDB”.
Index Terms—Cloud computing, encryption mechanisms,
homomorphic encryption, oder preserving encryption,
CryptDB.
