I am sharing the project ppt and u can edit it as i am leaving the space for your names.

2. A secure way for key distribution
without any secure communication
channels, and the users can securely
obtain their private keys from group
manager. Our scheme can achieve fine-
grained access control, any user in the
group can use the source in the cloud
and revoked users cannot access the
cloud again after they are revoked.
ABSTRACT

3. A cryptographic storage system that
enables secure data sharing on
untrustworthy servers based on the
techniques that dividing files into file
groups and encrypting each file group
with a file-block key.
EXISTING SYSTEM

4. We provide a secure way for key
distribution without any secure
communication channels. The users
can securely obtain their private keys
from group manager without any
Certificate Authorities due to the
verification for the public key of the
user.

12. Our scheme can achieve fine
efficiency, which means previous
users need not to update their
private keys for the situation either
a new user joins in the group or a
user is revoked from the group.
