摘要：Nowadays, people are aware of Online Social Networks. Several online social networks are benefitted by
regular people for their piece of work. Currently, almost online social networks are based on the centralized systems.
As these centralized systems gathers huge information at the single provider, that is risk for the privacy of user’s
personal data. To knock out the problem of centralized systems, new concept is brought to existence i.e., Decentralized
Online Social Network. As a substitute of centralized systems, Decentralized Online Social Network distributes its data
among numerous servers or within multiple users. This paper concentrates on the challenges of privacy and secrecy for
the information of users that is communicated on the group. Fresh solutions have to be discovered to lessen existing
difficulty. First solution can be the reduction of re-encryption process of documents before sharing it, when the group’s
size keeps varying. Second solution to the existing difficulty can be to moderate the dependency of keys for the fear of
any unknowing sudden changes in the group. Present solutions lack in achieving the above standards. Our methodology
insists single time encryption for each file and there is no necessity to revise keys after user’s addition or removal from
the group.
