Quantum Digital Signature Scheme Based on Finite Automata

Abstract

A quantum digital signature is the quantum cryptographic primitives that combine classical digital signature and quantum mechanics to provide unconditional security for the identity of the sender and the integrity of the classical messages. Currently, lots of quantum digital signature schemes have been investigated. In this paper, we propose a new quantum digital signature scheme based on finite automata and show its security against existing attacks. Finally, the noteworthy features like no entangled states are indicated.
