本篇論文結合不同類型的使用者，在非對稱式量子環境中提出了在第三方幫助下的使用非對稱量子能力之中介認證式輕量化量子金鑰分配協定。首先，本論文提出了參與者們透過半誠實的第三方的協助分享一把金鑰，在此量子金鑰分配協定中，兩個參與者其中一位為傳統使用者，另一位為輕量化使用者。接著，藉由引入完全不誠實的第三方並透過其具備完全的量子能力以及完全不可信的特性，提出使用半誠實第三方與完全不誠實第三方之使用非對稱量子能力之中介認證式輕量化量子金鑰分配協定，進一步降低半誠實第三方的負擔。此外，在上述提出的安全協定中，參與者們進行通訊時不需要使用到假設出的理想傳統認證通道，並且參與者皆為完全不同類型的參與者。因此所提出的使用非對稱量子能力之中介認證式輕量化量子金鑰分配協定在運用上更加彈性且靈活，並能應用於不同環境。最後，在集體攻擊下，我們透過安全證明來證實所提出的協定式安全的。

This thesis proposes a mediated authenticated lightweight quantum key distribution (MALQKD) protocols with asymmetric quantum capabilities between participants without authenticated classical channel. First, this thesis proposes a protocol in which the two participants with different asymmetric quantum capabilities to share a key with the help of a semi-honest TP. In the protocol, one participant is a classical user, and the other is a lightweight user. Further, by introducing an untrusted TP, and through untrusted TP’s full quantum capability and completely untrustworthy characteristics, we propose an MALQKD with a semi-honest TP and an untrusted TP protocol to further reduce the quantum burden on the semi-honest TP. Additionally, in the prior-proposed protocols, participants do not have to assume the existence of an ideal authenticated classical channel while communicating, and are all of different types. Therefore, the proposed MALQKD protocols are more flexible and can be applied to different environments. Finally, the security analysis demonstrates that the proposed protocols are robust against collective attacks.
