Delegatability of an Identity Based Strong Designated Verifier Signature Scheme
Xun Sun, Jianhua Li, Yin Hu, Gongliang Chen · Informatica · 2010
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. However, in this paper, we show that this scheme is actually delegatable.
