Lightweight group key distribution schemes based on pre‐shared pairwise keys

Lein Harn, Ching-Fang Hsu, Zhe Xia

In a secure communication, a one‐time session key is needed to be shared among all participants. Most well‐known key distribution schemes, such as Diffie–Hellman public‐key key distribution scheme invented in 1976 and quantum key distribution scheme invented in 1984 (also called the BB84 scheme), can only allow two users to share a key in conventional one‐to‐one communications. There are many research papers in the literature to propose group key distribution schemes for multiple participants in modern group communications. In this study, the authors propose lightweight group key distributions using pre‐shared pairwise keys. The authors first propose a three‐party group key distribution scheme. They then extend the basic three‐party scheme to establish a group key for a large size of group communications. The proposed generalised schemes can be based to any type of pairwise key distribution schemes, e.g. either quantum or non‐quantum. Moreover, both generalised multi‐party group key distribution schemes are lightweight. The main operations in the proposed schemes are key comparison between two or more than two keys (i.e. logic XOR operation) and the computation of key derivation functions.

On the lightweight authenticated semi-quantum key distribution protocol without Trojan horse attack

Jun Gu, Tzonelih Hwang

Recently, Tsai et al. (Laser Phys. Lett. 17, 075202, 2020) proposed a lightweight authenticated semi-quantum key distribution protocol for a quantum participant to share a secret key with a classical participant. However, this study points out that an attacker can use a modification attack to make both participants share a wrong key without being detected. To avoid this problem, an improvement is proposed here.

An efficient lightweight mediated semi-quantum key distribution with single-particle states

Yihua Zhou, Xiang-Rui Li, Yu‐Guang Yang +1 more

Abstract In this paper, we propose an efficient lightweight mediated semi-quantum key distribution (LM-SQKD) protocol, which enables two lightweight participants to securely establish a shared key with the help of an untrusted third party (TP). Compared with existing M-SQKD protocols, our protocol significantly reduces the overall quantum burden and improves the qubit efficiency, where TP only needs to prepare and measure qubits in the X basis and two lightweight participants are just required to execute three unitary operations and reflect qubits. Furthermore, the detailed security analysis verifies that the proposed protocol can against three well-known attacks.
