Abstract: We generalize the Strong Boneh-Boyen (SBB) signature scheme to sign vectors (GSBB). We show that if a particular (but most natural) average case reduction from SBB to GSBB exists, then the Strong Diffie-Hellman (SDH) and the Computational Diffie-Hellman (CDH) have the same worst case complexity.
