Cost-Effective Authentic and Anonymous Data Sharing with Forward Security
Abstract— Cost-Effective Authentic and Anonymous Data Sharing with Forward Security. Data sharing has never been easier with the advances of cloud computing, and an accurate analysis on the shared data provides an array of beneﬁts to both the society and individuals.< Final Year Projects 2016 > Data sharing with a large number of participants must take into account several issues, including efﬁciency data integrity and privacy of data owner. Ring signature is a promising candidate to construct an anonymous and authentic data sharing system. It allows a data owner to anonymously authenticate his data which can be put into the cloud for storage or analysis purpose. Yet the costly certiﬁcate veriﬁcation in the traditional public key infrastructure (PKI) setting becomes a bottleneck for this solution to be scalable.
