Special Issue Information

Dear Colleagues,

As internet and information technology is evolving, our everyday life is becoming more and more digital, connecting our physical world with cyberspace. In the emerging cyberphysical systems, cryptography plays a critical role for harmoniously connecting the physical and the cyber world. On one hand, traditional cryptographic algorithms lay the foundations for building robust and reliable systems. On the other hand, quantum resistant cryptography plays a key role to future-proof the connected world. Ultimately, both traditional and post-quantum cryptography are the pillars for establishing trustworthy relationships in emerging and future systems.  

This Special Issue provides a broad overview of hot topics and open issues by covering areas that include many different theoretical and technological aspects involved in traditional and post-quantum cryptography.

Specific topics of interest include, but are not limited to:

  • Quantum cryptography;
  • Quantum key distribution;
  • Code-based, lattice-based, hash-based, isogeny-based, multivariate cryptography;
  • Standardization efforts in quantum resistant cryptography;
  • Attacks on post-quantum cryptosystems;
  • Security models for post-quantum cryptography;
  • Physical layer authentication for cyberphysical systems;
  • Fuzzy cryptography, PUFs, and biometrics;
  • Security and privacy techniques for energy, transportation, healthcare, and medical systems;
  • TPM and TEE security;
  • Cryptographic solutions in supply chain security;
  • Hardware implementations of cryptographic algorithms;
  • Side channels and fault attacks for cyberphysical systems;
  • Deanonymization and cryptanalysis;
  • Lightweight cryptography for the IoT and sensors;
  • Blockchain and cryptocurrencies;
  • Homomorphic encryption;
  • Security and anonymity for 5G/6G mobile networks;
  • Verifiable credentials and attribute-based credentials;
  • Searchable encryption and privacy preserving data mining for cloud technologies;
  • Machine learning and cryptography.

This work details the theory and implementation of a multi-wavelength quantum key distribution (QKD) emulation system with a physical unclonable function (PUF). Multi-wavelength QKD can eliminate the need to share a subsection of the final key for eavesdropper detection and allow for ternary and quaternary data transmission. The inclusion of the PUF adds an additional layer of security. We provide preliminary error analysis of our emulation system. To support this work, we introduce a bitwise transform operator that enables binary output of the PUF to satisfy the ternary and quaternary input requirements of the QKD system. Full article

The development of increasingly sophisticated quantum computers poses a long-term threat to current cryptographic infrastructure. This has spurred research into both quantum-resistant algorithms and how to safely transition real-world implementations and protocols to quantum-resistant replacements. This transition is likely to be a gradual process due to both the complexity and cost associated with transitioning. One method to ease the transition is the use of classical–quantum hybrid schemes, which provide security against both classical and quantum adversaries. We present a new combiner for creating hybrid encryption schemes directly from traditional encryption schemes. Our construction is the only existing proposal in the literature with IND-CCA-security in the classical and quantum random oracle models, respectively. Full article

Attribute-based encryption (ABE) cryptography is widely known for its potential to solve the scalability issue of recent public key infrastructure (PKI). It provides a fine-grained access control system with high flexibility and efficiency by labeling the secret key and ciphertext with distinctive attributes. Due to its fine-grained features, the ABE scheme is a protection layer in securing users’ data and privacy in big data processing and analytics. However, quantum computing, new technology on the horizon that will transform the security and privacy environment, has begun to appear. Like the conventional ABE schemes, present cryptography is not excluded from the impacts of quantum technology as they are not made to be quantum-resistant. While most recent surveys generally touched on the generic features of attribute-based encryption schemes such as user revocation, scalability, flexibility, data confidentiality, and scope in pairing-based ABE schemes, this survey investigated quantum-resistant ABE schemes in securing big data. This survey reviews the challenges faced by the recent ABE cryptography in the post-quantum era and highlights its differences from the conventional pairing-based ABE schemes. Subsequently, we defined the criteria of an ideal quantum-resistant ABE scheme. Additionally, existing works on quantum-resistant ABE schemes are reviewed based on their algorithms design, security and functionalities. Lastly, we summarized quantum-resistant ABE schemes’ ongoing challenges and future works. Full article
