Cloud Computing is becoming the heart or the central theme for
all sort of computing. Cloud is a remote place, at which user can

more services on rent. This paper presents a brief introduction to
the concept of clouds & its services. This paper also presents the
issues related to the security of data in cloud environment. A
few modern attribute based encryption models for the data

security model for the cloud computing environment. The
proposed model combines the advantages of the hierarchical
