Development Of An Authentic And Anonymous Data Sharing Using Ring Signature

Abstract

Data sharing with a huge number of participants consider many concerns, together with efficiency, data integrity and privacy of data owner. Data sharing became tedious with the cloud computing that can be addressed by the precise analysis on the shared data .It will make accessible a range of profits to both the society. Ring signature provides authentication to user data that can be placed in to the cloud for storage or scrutiny purpose. In this technique costly certificate verification in the traditional public key infrastructure (PKI) setting becomes a holdup.  In Identity-based (ID-based) ring signature, process of certificate verification is eliminated. In this paper, the security is improved by forward security. In this process any user a secret key will be compromised.
