With the rapid development of information science, the privacy protection of medical data has been paid close attention. Given that traditional encryption technology has some technical loopholes in the intractability of large prime number factorization and information transmission security, the security of medical data transmission based on classical encryption is challenged. Thanks to the uncertainty principle and quantum non-cloning theorem, quantum communication technology is relatively secure. The secure quantum state transfer protocol is also a popular topic in information transmission now. Thus, based on quantum technologies such as quantum teleportation, it is imperative to realize safe transmission in smart medical care. Based on the secure transmission of shared secret states, this paper designs a secure transmission model of medical data between multiple clients and servers, which does not need a trusted client node, thus improving the performance of resisting node attacks. In addition, by using qiskit, the protocol simulation is conducted. Compared with traditional medical data transmission, quantum state data transmission is more secure and undecipherable, achieving the secret transmission of medical data.

Internet of Vehicles (IoV) is a hot research issue at home and abroad. However, with the development of intelligent, sharing and network connection of IoV technology, the security protection of IoV communication has become a focus. Traditional encryption technology relies on encryption systems, whose security relies on the difficulty of solving mathematical problems and cannot resist quantum computing attacks. The security of classical encryption-based data transmission has been challenged. Therefore, it is imperative to realize secure transmission in IoV based on quantum technologies such as quantum teleportation. In this paper, based on the secure transmission of shared secret states, the author has designed a model for the secure transmission of data among multiple vehicles, which does not require trusted client nodes and thus improves the performance against node attacks. Further, considering the communication distance in practical situations, the quantum repeater is introduced to construct a quantum state transmission model based on the quantum repeater in IoV to realize secure communication among multiple vehicles. Compared with traditional data transmission, the quantum state transmission data is more secure and unbreakable, which provides a new idea for constructing secure communication in IoV.
In the field of smart healthcare, video consultation has become a key way to provide medical services for remote patients. In this process, it is essential to ensure the legal identity of both parties to the communication and to protect patient privacy data from unlawful interception and tampering. Therefore, a controlled quantum authentication confidential communication protocol is proposed by using the entanglement exchange ability and measurement correlation of Bell states. With the assistance of a trusted third party, the protocol first achieves the mutual authentication of the communication parties, so as to prevent malicious users from communicating by pretending to be medical specialists or patients. The trusted party then further assists the communicating parties in generating two implicit shared keys, which they use to encrypt the message and its digest, ensuring that the patient's sensitive data is not intercepted or tampered with. In addition, the quantum sequences are transmitted only once in the channel, reducing the loss and noise effects caused by multiple transmissions. Security analysis shows that the protocol can effectively resist participant attacks and outside attacks. In addition, performance analysis provides computation in terms of qubit efficiency and experimental simulation results of the protocol.
The vast amounts of data and the growing number of attacks in the smart grids (SGs) are consequences of the huge reliance on information and communication technology, that is further posing serious risks to the confidentiality and integrity of the power data. On the other hand, recent advancements in quantum cryptography are emerging as foundation for secure communication protocols, offering robust defenses against potential cyber threats in SGs. In response to the imperative challenge of secure data transmission, a quantum cryptography based unconditionally secure data transmission model is proposed that integrates quantum key distribution (QKD) with classical encryption. Furthermore, truly random encryption keys generated through quantum random number generator (QRNG) are utilized that assists to overcome the limitations of pseudo-random number generator and leads to the highly immune data security mechanism. The efficacy of proposed model is evaluated through experimental results obtained over classical simulator along with real quantum computers accessed through the IBM Qiskit platform. The statistical analysis conducted on the resulting quantum states showcases a high degree of accurate measurements, thereby confirming the relevance of the proposed work.
With the widespread adoption of Internet of Things (IoT) technologies in healthcare systems, security issues related to user privacy during data transmission and sharing have become increasingly prominent. To address these challenges, this paper proposes a medical privacy protection and secure sharing scheme based on Quantum Key Distribution (QKD). The scheme integrates multiple technologies, including blockchain, smart contracts, zero-knowledge proofs, and Chebyshev chaotic mapping, to ensure secure data sharing and access control among multiple communication entities. Compared with existing solutions, our approach enhances key management security through quantum keys and improves communication resilience against attacks by leveraging chaotic systems. User identity privacy is protected via zero-knowledge proofs. Under the random oracle model, the security of the proposed scheme is formally proven. Moreover, comparative experiments with existing protocols demonstrate the scheme's comprehensive advantages in terms of security and performance, evaluated across throughput, computational overhead, communication overhead, and storage overhead.
With the digitization and networking of medical and health data, intelligent medical devices are widely used to monitor patient health status and provide personalized medical services. However, these devices involve a large amount of personal health data and must ensure data security. The data security and privacy protection in the new complex network environment has become one of the important challenges in the field of healthcare. This study aims to propose a post quantum attribute based authentication key agreement protocol applicable to intelligent healthcare, to address the security risks and risks of medical data communication under traditional cryptographic systems. This new protocol is based on attribute authentication encryption technology without certificates on the grid, which completes mutual authentication and establishes secure communication through attribute and access control policies, and can optimize the deployment of certificate system components in public key infrastructure. Meanwhile, this scheme belongs to the post quantum cryptography protocol and has the ability to resist quantum computing attacks. Based on comprehensive analysis, this scheme can achieve certain advantages in execution efficiency and security, and can provide a more reliable choice for secure communication in the field of intelligent healthcare.
With the swift development of healthcare digitization we have access to an exponentially growing amount of extremely sensitive patient data that requires advanced security. However, now with the advent of quantum computing we are faced with a very real risk of exposing medical data in ways we never thought possible through traditional encryption. In this chapter, we will discuss the critical need for quantum-safe encryption to protect against quantum-based attacks on electronic health records, telemedicine communications, and IoT-enabled medical devices. We will review existing cryptography standards (i.e. RSA, ECC) in a post-quantum world, and consider new quantum-resistant algorithms like lattice-based, hash-based, and multivariate algorithms outlined in NIST's Post-Quantum Cryptography (PQC) standardization program. We will also highlight how quantum secure encryption will revolutionize the security of healthcare data in terms of data integrity, privacy protection, and secure communications.
