Abstract

Abstract—A quantum communication scheme for blind signa-ture is proposed based on two-particle entangled quantum system to create a novel systemetrical quantum cryptosystem. All the messages are encrypted by the private key of the sender Alice during the communication and the authenticity verification of signatures and an arbitrator’s batch efficient proxy signature is applied. It demonstrates that a large number of blind signatures can be derived with the characteristics: impossibility of forgery, impossibility of disavowal by the signatory and impossibility of denial by the receiver. The security of our scheme depends on the two-particle entangled system which cannot be deterministically intercepted. Index Terms—Quantum communication, Blind signature, Proxy signature, Quantum signature, Quantum cryptography.

Constructions of Quantum Blind Signature Based on Two-Particle-Entangled System

Lixin Lin, Ying Guo

Based on a three-dimensional quantum system which is used to distribute the keys and create the strings of quantum-trits (qutrits) for messages, the batch signature is proposed to create a novel quantum cryptosystem. All of the messages, which are expected to be signed, are encrypted by the private key of the sender during communications. Different from the classical blind signature, an identity verification, an authenticity verification of signatures and an arbitrator's efficient batch proxy signature are simultaneously applied in the present scheme.

The advances in hardware speed has being rapidly increased rapidly in the recent years, which will lead to the ability to decrypt well known decryption algorithms in short time.This motivated many researchers to investigate better techniques to prevent disclosing and eavesdropping of communicated data.Quantum Cryptography is a promising solution, since it relies on the prosperities of quantum physics that ensure no change in the quantum state without the knowledge of the sender/receiver.Quantum Communication Scheme for Blind Signature with Two-Particle Entangled Quantum-Trits was proposed by Jinjing et al. [1] That scheme uses qutits during the communications and the process of the encryption is not clearly defined.In this paper we suggest a modification of Jinjing et al. protocol using qubits and qutrits during the encryption and decryption which proposed by Zhou et al. [2] The proposed algorithms enhances the efficiency of that scheme and creates a quantum cryptosystem environment to exchange the data in a secure way.During the communications, all the messages are encrypted using the the private key of the sender and a third party verifies the authenticity and the blindness of the signature.

Motivated by proxy signature and blind signature for the secure communications, the batch signature is proposed to create a novel quantum cryptosystem. It is based on three-dimensional two-particle-entangled quantum system which is used to distribute the quantum keys and create strings of quantum-trits (qutrits) for messages. All of the messages, which are expected to be signed, are encrypted by the private key of the message owner during communications. Different from the classical blind signature, an authenticity verification of signatures and an arbitrators efficient batch proxy signature are simultaneously applied in the present scheme. Analysis of security and efficiency shows that it enables us to achieve a large number of quantum blind signatures for quantities of messages with a high efficiency with the arbitrators secure batch proxy blind signature.

Blind Digital Signature schemes with four particle entanglement states

S. Suparshya Babu, Razan Abdulhammed, Khaled M. Elleithy +1 more

Quantum Digital Signature (QDS) schemes provides authenticity of information that is guaranteed by quantum mechanics. This paper compares the blind signature schemes with two and three-bit quantum state bits and provides a implementation for the four quantum states. We proposed a technique where four partial entangled states are used to implement the blind signature scheme. The proposed technique improves the reliability factor of the scheme in terms of its encryption and decryption using quantum cryptosystem for interchanging the data in a protected mode. In the communication system, the encryption of messages was done with the help of the sender's private key. The third party verifies its authenticity along with blindness of the signature. Furthermore, future research trends were presented with a security analysis.
