We present a quantum signature scheme using a single qubit rotation operator. In this protocol, the trusted center confirms the quantum signature and thus conforms with other quantum signature schemes. Utilizing the unitary properties of a single qubit rotation operator and Pauli operators, our protocol provides signature security and enhances the efficiency of communication. In addition, our protocol -using only a single qubit measurement -facilitates the ease of implementation and enhances convenience for users. The security of the protocol is analyzed.

“…Over a decade, the slowpacing of experimental realization [2], [3], [4] hampered the progress of QDS and other quantum protocols. Alternatively, we consider to construct a security model which can facilitate exploration of quantum one-way function to more scenarios and security analysis of related quantum cryptographic protocols, such as quantum digital signature schemes [5], [3], [6] and quantum public-key encryption schemes [7], [8].…”

Security analysis of quantum cryptographic protocols is mostly presented with situational quantum attacks and still lacks general analysis methods. As an effective analysis tool in classical cryptography, the random oracle (RO) model has been used to design cryptographic protocols and give rigorous proofs of security over 20 years. In this work, with reference to the classical RO model, we provide a general security analysis tool, namely, the quantum random oracle (QRO), for facilitating the security analysis of quantum cryptographic protocols, especially protocols based on quantum one-way function. QRO is used to model quantum one-way function and different queries to QRO are used to model quantum attacks. A typical application of quantum one-way function is the quantum digital signature, whose progress has been hampered by the slow pace of the experimental realization. Alternatively, we use the QRO model to analyze the provable security of a quantum digital signature scheme and elaborate the analysis procedure. This work is presented in detail in [1].

In this work, a quantum computing based secret key distribution system is proposed. Quantum gates based encryption and decryption circuits are designed and can be used along with conventional encryption schemes such as the Data Encryption Standards (DES), XoR Cipher and Substitution Cipher etc., in the presentation layer. The quantum communication model is implemented and analyzed for both ideal and noisy channel. Using this model if the channel is eaves dropped, the sender and receiver will detect the eavesdropping attempt, the key will be discarded and another key is retransmitted.
