“…An SQSS protocol without the need for measurement was proposed in [97]. A d-dimensional protocol was proposed in [98] which also did not require classical users to measure and supported multiple (beyond two) classical users. A secret sharing protocol using W -states for encoding (as opposed to Bell states or GHZ states) was developed in [99].…”

Quantum key distribution (QKD) protocols allow two parties to establish a shared secret key, secure against an all powerful adversary. This is a task impossible to achieve through classical communication only; indeed, to distribute a secret key through classical means requires one to assume computationally bounded adversaries. If, however, both parties are "quantum capable" then security may be attained assuming only that the adversary must obey the laws of physics. But "how quantum" must a protocol actually be to gain this advantage over classical communication? This is one of the questions semi-quantum cryptography seeks to answer.Semi-quantum communication, a model introduced in 2007 by M. Boyer, D. Kenigsberg, and T. Mor (PRL 99 140501), involves the use of fully-quantum users and semiquantum, or "classical" users. These classical users are only allowed to interact with the quantum channel in a limited, classical manner. Originally introduced to study the key-distribution problem, semi-quantum research has since expanded, and continues to grow, with new protocols, security proof methods, experimental implementations, and new cryptographic applications beyond key distribution. Research in the field of semi-quantum cryptography requires new insights into working with restricted protocols and, so, the tools and techniques derived in this field can translate to results in broader quantum information science. Furthermore, other questions such as the connection between quantum and classical processing, including how classical information processing can be used to counteract a quantum deficiency in a protocol, can shed light on important theoretical questions.This work surveys the history and current state-of-the-art in semi-quantum research. We discuss the model and several protocols offering the reader insight into how protocols are constructed in this realm. We discuss security proof methods and how classical post-processing can be used to counteract users' inability to perform certain quantum operations. Moving beyond key distribution, we survey current work in other * semi-quantum cryptographic protocols and current trends. We also survey recent work done in attempting to construct practical semi-quantum systems including recent experimental results in this field. Finally, as this is still a growing field, we highlight, throughout this survey, several open problems that we feel are important to investigate in the hopes that this will spur even more research in this topic.

“…Subsequently, various cryptographic protocols have been proposed in the semi-quantum environment. Among these semi-quantum cryptographic protocols, semi-quantum secret sharing (SQSS) [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] is considered to be an important research branch. In 2011, Li et al [48] proposed the first SQSS protocol that allows a quantum dealer Alice to share her secrets with two classical agents, Bob and Charlie, using GHZ-type states.…”

“…[45] proposed the first semi-quantum key distribution (SQKD) protocol, various quantum protocols were proposed, in which the semi-quantum secret sharing (SQSS) protocol is also an important research issue. There are literatures [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] proposed for this issue. In 2011, Li et al [46] proposed the first SQSS protocol to let the dealer Alice (the quantum user) share her secrets with two agents, Bob and Charlie (the classical users) by using GHZtype state.…”

This study proposes the first multiparty mediated semi-quantum secret sharing (MSQSS) protocol to overcome two existing challenges in current semi-quantum secret sharing protocols: (1) dealer must be the quantum user, and (2) classical users must be equipped with Trojan horse detectors. * In the proposed MSQSS protocol, a classical dealer can share secrets with multiple classical agents via the help of a dishonest quantum third party. Security analysis is performed to prove that the proposed protocol cannot suffer from a collective attack, a collusion attack, or a Trojan horse attack. Furthermore, the proposed MSQSS protocol is more lightweight than existing SQSS protocols because the classical user is equipped with only two quantum capabilities.
