The entire protocol is broken in three phases: Key Generation, Signature and Verification. This scheme is presented between PKG, a Signer and a Verifier.</br>
Like other QDS protocols, it is divided into two phases: Distribution (Key Generation) and Messaging (signature and verification). This scheme is presented between PKG, a Seller and a buyer.</br>
* '''Key Generation''': In this method, the PKG generates a private key for the Signer and sends the same. This transaction can take place on both secure and insecure channels.

** Using identity-based encryption, Signer's public key is generated using their personal public information like email or ID card. This public key is accessible on open channels.
