In this paper, we survey the state of research on Identity Based Blind Signature. We start from reviewing the basic concepts of identity based encryption and blind signature schemes and subsequently review the framework of ID-based blind signature, and classification of ID-based blind signature. Lastly, we discuss the applications of ID-based blind signature. Keywords— Identity Based Encryption...
