Quantum public key encryption scheme with four states key

Zhixin Liu, Qiaoling Xie, Yongfu Zha +1 more

Abstract Asymmetric encryption has some important applications in the field of communication. In classical computers, most public key encryption schemes are designed based on computational assumption. In other words, they can ensure computational security. When the computing power is large enough, it will pose a threat to these encryption schemes. We propose a quantum public key encryption scheme which based on properties of quantum physics. Our scheme realizes encryption and decryption with few resources and does not rely on any computational assumption. The key in our scheme consists of classical bits and qubits. Where the private key are classical bit and public key are qubits. The public key are generated through private key. We analyze the performance and security of the scheme. Our scheme ensures the information-theoretic secure and can be implemented easily.

Partially coherent optical chip enables physical-layer public-key encryption

Bo Wu, Wenkai Zhang, Hailong Zhou +3 more

Public-key encryption is essential for secure communications, eliminating the need for pre-shared keys. However, traditional schemes such as RSA (Rivest-Shamir-Adleman) and elliptic curve cryptography rely on computational complexity, making them increasingly susceptible to advances in computing power and algorithms. Physical-layer encryption, which leverages the intrinsic properties of physical systems, offers a promising alternative with security rooted in physics. Despite progress in this field, public-key encryption at the optical layer remains largely unexplored. Here, we propose a novel optical public-key encryption scheme based on partially coherent light sources. The cryptographic keys are encoded in the incoherent optical transmission matrix of an on-chip Mach-Zehnder interferometer mesh, providing high complexity and resilience to computational attacks. We experimentally demonstrate encrypted image transmission over 40 km of optical fiber with high decryption fidelity and achieve a 10 Gbit/s optical encryption rate using a lithium niobate photonic chip. This represents the first implementation of public-key encryption at the physical optical layer. The approach offers key advantages in security, cost, energy efficiency, and compatibility with commercial optical communication systems. By integrating public-key encryption into photonic hardware, this work opens a new direction for secure and high-speed optical communications in next-generation networks.

A Lattice-Based Public Encryption with Key Search Scheme for Wireless Sensor Networks

Fugeng Zeng

With the rapid progress in technology, wireless sensor networks (WSNs) have attracted people's interest in the research community. However, due to the limited node communication and computing power, the traditional public key encryption algorithm can't be effectively applied. And as step into post-quantum era, pairing related assumption is fragile. Lattice is an ideal choice for building secure encryption scheme against quantum attack. Based on this, we propose a public encryption with key search scheme from lattice for wireless sensor networks. Compared with the existing public searchable encryption algorithm, the proposed encryption algorithm requires less computation time and achieves more security level.
