In 2007, Kancharla et al. proposed an identity-based strong designated verifier signature (IBSDVS) scheme based on bilinear pairings, and claimed it unforgeable and non-delegatable...

A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based o...
