Abstract
Distributed Cloud Environment (DCE) focuses
mainly on securing the data and safely shares it to the user. Data
leakage may occur by the channel compromising or with the key
managers. It is necessary to safeguard the communication
channel between the entities before sharing the data. In this
process of sharing, what if the key managers compromises with
intruders and reveal the information of the user’s key that is used
for encryption. The process of securing the key by using the user’s
phrase is the key concept used in the proposed system “Secure
Storing and Sharing of Data in Cloud Environment using User
Phrase (S3DCE). It does not rely on any key managers to generate
the key instead; the user himself generates the key. In order to
provide double security, the public key derived from the user’s
phrase also encrypts the encryption key. S3DCE guarantees
privacy, confidentiality and integrity of the user data while storing
and sharing. The proposed method S3DCE is more efficient in
terms of time, cost and resource utilization compared to the
existing algorithm DaSCE (Data Security for Cloud Environment
with Semi Trusted Third Party) [22] and DACESM (Data Security
for Cloud Environment with Scheduled Key Managers) [23]
