Embodiment Construction

[0051] In order to further illustrate the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are for reference and description only, and are not intended to limit the protection scope of the present invention.

[0052] Before introducing specific schemes, the present invention first describes some necessary representations here. First of all, for the arbitration quantum signature scheme proposed by the present invention, three participants Alice, Bob, and Trent are introduced, representing signer, receiver (verifier) ​​and arbitration (trusted third party) respectively.

[0053] Such as figure 1 , Figure 4 As shown, this embodiment discloses a public key arbitration quantum signature protocol based on quantum block encryption, including the following steps S1 to S3:

[0054] S1. Through quantum key distribution, asymmetric quantum key sharing is shared between t...

Abstract

The invention discloses a public key arbitration quantum signature protocol based on quantum block encryption, which belongs to the technical field of quantum secret communication and comprises quantum key sharing among a signer, a receiver and arbitration through quantum key distribution. The signer prepares two parts of sub-messages and one part of sub-signature, sends one part of sub-message tothe receiver and sends the quantum signature to arbitration; And the receiver verifies the quantum signature under the constraint condition provided by arbitration. The protocol provided by the invention not only can ensure the security, but also has a better practical application value.

Description

technical field [0001] The invention relates to the technical field of quantum secure communication technology, in particular to a public key arbitration quantum signature protocol based on quantum block encryption. Background technique [0002] With the rapid development of communication technology and computer technology, electronic information has become a part of people's daily work and life. Informatization has expanded the way for people to understand the world, and it has also provided infinite possibilities for people to transform the world. However, unprecedented security threats are also intensified along with the deepening of informatization, so it is particularly urgent to explore and study theories and technologies to ensure information security. [0003] Digital quantum signature is the core technology to realize identity authentication and protect data integrity, and is the key theoretical basis for implementing information system access control and secure e-c...
