文摘

Many novel quantum digital signature proposals have been proposed, which can effectively guarantee the information-theoretic security of the signature for a singe bit against forging and denying. Using the current basic building blocks of signing a single bit, we give a new proposal to construct an entire protocol for signing a long message. Compared with the previous work, it can improve at least 33.33% efficiency.
