Digital signature: Quantum chaos approach

Digital signature: Quantum chaos approach

The quantum mechanics applied by quantum digital signatures (QDSs) is applied to guarantee the nonrepudiation, unforgeability, and transferability of a signature. Previously, the security of QDSs schemes only depended on the length of the signature. Also, they required unreliable security channels and have been written for one-bit messages. In this paper, quantum digital signature schemes based on DNA sequence and quantum mixed open systems is introduced. In our schemes, using the quantum mixed open systems when signing up, security increases against repudiation and forgery. Furthermore, to sign a regular message, repeating the signature steps is half as much as the previous ones.
