Data Sharing Over the Cloud Based on Ring Signature

Abstract

Cloud computing, which provides on demand delivery of services, wherever and whenever, mainly focuses on data sharing over the Internet. So, when data sharing among group of participants from same or dissimilar environment is involved, it may face compromising situation in terms with integrity, confidentiality and privacy of content/data as well as of data owner. One of the features of ring signature is to construct confidential what is more, unknown information sharing framework among the participants group. The ring signature can be used to provide signer’s privacy as well as user’s secrecy. But, for ring mark or signature, the certificate validity verification processing remains a pinch point which does not permit any framework to be flexible. So, to defeat this, the ID-based ring mark or signature can be used. Further, forward security is being appended to make ID-based ring mark or signature increasingly certain, on the grounds that regardless of whether single key used in one transaction have been undermined, still all recently created marks or signatures remain uncompromised and legitimate with the forward security theory use. In this, data sharing over the cloud based on ring signature system, ID-based ring mark or signature added with forward security is moreover improvised by appending Weil pairing, which keeps any key secure irrespective of its size, and it also has less time and space multifaceted nature and hence saves power. All these combined together is essential to construct scalable information sharing framework. So, this paper provides proficient and substantial application of the above-mentioned framework.
