A Highly Secure Quantum Communication Scheme for Blind Signature using Qubits and Qutrits

© ASEE 2014The 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
