摘要

隨著科技的推移與進步，人們對資訊安全日益看重，在這通訊發達與駭客猖獗的時代，傳統SIM卡與eSIM的集中式儲存方式、資料存放的問題與傳輸的方法，皆帶來了安全性的隱憂，以及隱私性問題。為此，本研究提出了一種區塊鏈為基礎的SIM架構，以區塊鏈作為分散式帳本，透過與智能合約的結合，利用去中心化與不可竄改的等特性，將改變過去集中式儲存所帶來的安全性問題，同時也確保了資料的完整性，其次通過二次加密的方式，也使得隱私性問題獲得了改善，最後我們也介紹了如何使用我們所提出的架構來實現SIM的主要功能。

With the progress and advancement of technology, people pay more attention to information security. In the age of advanced communications and rampant hackers, the centralized storage of traditional SIM cards and eSIMs, the data storage and transmission all bring security concerns and privacy issues. Therefore, the study proposes a block-chain-based SIM architecture, which uses the block-chain as a distributed ledger through the combination with smart contracts, and the use of decentralized and non-manipulative features will change the security problems caused by centralized storage in the past. In our approach, the problem has also been improved to ensure the integrity of the data as well. Finally, we also introduced how to use our proposed architecture to implement the main functions of SIM.
