The protocol under discussion (1) was the first version of Quantum Digital Signatures with only prepare and measure QKD components. The assumption authenticated quantum channel would render it useless as authenticated quantum channel is a more complex protocol. Thus in (6), a variant of this protocol overcomes this assumption by using a Key generation protocol (not QKD) for authentication where, instead of Seller, Buyer and Verifier sends quantum public keys to the Seller to measure in randomly chosen basis and generate her private keys. Following description for various papers on QDS protocols and their variants have been written keeping in mind the hardware requirements, assumptions, security and method used. One of the papers discusses generalisation of protocols to more than 3 parties and another one discusses security for iterating in case of sending multiple bits. | |||
