In this work we analyze the BG14 digital signature, and show that its security-proof is incomplete in the sense that a necessary security check is missing in its sign algorithm. Moreover, we offer an alternative approach for the phase 2 security-proof of the BG14 scheme. These two contributions are summarized in our digital signature scheme Π.
