The integrity and authenticity of the message, and it's nonrepudiation, are provided by digital signatures. We introduce quantum digital signature schemes based on Quantum Dots, where DNA coding is used to increase the intricacy of phase space. We attain the optimal security standard by constructing a deterministic dynamic system in a finite phase space with n points and by using symbolic dynamics. Also, given the chaotic Substitution box(S-box), a confusing step has been added for greater security. The introduced quantum dynamical map is used to create procedures to resistance again the common attacks in the digital signature such as non-repudiation, unforgeability, and transferability. Its security depends on the length of the signature, directly. [ABSTRACT FROM AUTHOR] |
