  Abstract

In recent years, Government of India has introduced many Aadhaar based online services. Although these initiatives helped India compete in digital revolution across world and were acclaimed by many, they have also raised some concerns about security especially the privacy aspects. One of the initiative in this direction is eSign which provides an online electronic signature service to its subscribers. Although most of the security aspects are addressed by eSign, some of the privacy aspects are yet to be addressed. This paper presents a scheme to implement privacy enhanced eSign using Attribute based Signatures (ABS). For the practical and efficient realization of the scheme, a token based approach is proposed.
