We propose Panda, a novel public auditing mechanism for the integrity of shared data with efficient user revocation in the cloud. In our mechanism, by utilizing the idea of proxy resignatures, once a user in the group is revoked, the
cloud is able to resign the blocks, which were signed by the revoked user, with a re-signing key. As a result, the efficiency of
user revocation can be significantly improved, and computation and communication resources of existing users can be easily
saved. Meanwhile, the cloud, which is not in the same trusted domain with each user, is only able to convert a signature of
the revoked user into a signature of an existing user on the same block, but it cannot sign arbitrary blocks on behalf of either
the revoked user or an existing user. By designing a new proxy re-signature scheme with nice properties, which traditional
proxy re signatures do not have, our mechanism is always able to check the integrity of shared data without retrieving the
entire data from the cloud. Here we have to focus on data transmitted with secure manner and revocation in cloud in open
stack architecture with different techniques.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
