Fast and Proven Secure Blind Identity-Based Signcryption from Pairings [chapter]

Tsz Hon Yuen, Victor K. Wei
2005 Lecture Notes in Computer Science  
We present the first blind identity-based signcryption (BIBSC). We formulate its security model and define the security notions of blindness and parallel one-more unforgeability (p1m-uf).  ...  In the process, we also introduce a new security model for (non-blind) identity-based signcryption (IBSC) which is a strengthening of Boyen's.  ...  We present the first blind identity-based signcryption (BIBSC).  ...
