摘要:	區塊鏈技術是近年來備受關注的創新技術，以去中心化、安全性和透明性等特點而廣受推崇。區塊鏈已經廣泛應用於金融、供應鏈、健康醫療等多個領域，並在這些領域中帶來了許多顯著的改變和創新。本論文的研究目標在於探討區塊鏈技術在電力收費系統中的應用架構。目前在台灣，智慧電表的部署數量不斷增加，這些智慧電表能夠自動收集及傳輸用電資料。然而，在資料的傳輸過程中存在著資料竄改和未經授權使用的風險。為了解決這些問題，本論文提出了一個基於區塊鏈和IPFS星際檔案系統的架構，旨在提供更安全的解決方案，確保資料完整性並防止竄改。該架構中，智慧電表端將文件進行非對稱式的加密，保障文件的安全性，並將加密後的文件儲存到IPFS系統中。電力營運商通過區塊鏈獲取所需的資料，從而產生電費。為了評估系統的性能，在智慧電表端進行了一次多筆文件上傳測試，記錄了不同數量文件上傳的處理時間，在測試結果中發現影響時間的主要因素包括IPFS上傳所帶來的延遲以及區塊鏈的交互時間，透過這些測試結果更好地了解系統的效能表現。 ;Blockchain technology has been a highly regarded innovation in recent years, valued for its decentralized, secure, and transparent characteristics. It has been widely adopted in various sectors such as finance, supply chain, healthcare, and has brought significant changes and innovations in these fields. The research objective of this paper is to explore the application architecture of blockchain technology in the electricity billing system. In Taiwan, the deployment of smart meters is increasing, enabling the automatic collection and transmission of electricity usage data. However, there are risks of data tampering and unauthorized use during the data transmission process. To address these issues, this paper proposes an architecture based on blockchain and IPFS (InterPlanetary File System) to provide a more secure solution, ensuring data integrity and preventing tampering.In this architecture, the documents at the smart meter end are encrypted using an asymmetric encryption method to ensure their security, and the encrypted files are stored in the IPFS system. The power operator obtains the required data from the blockchain to generate electricity bills.To assess the system′s performance, a multi-file upload test was conducted at the smart meter end, recording the processing time for uploading different quantities of files. The test results revealed that the main factors affecting the time were the delays caused by IPFS uploads and the interaction time with the blockchain, providing a better understanding of the system′s performance.
