Comparative Analysis of Security Features and Risks in Digital Asset Wallets
Hyung-Jin Lim, Sokjoon Lee, Moonseong Kim, Woochan Lee · Electronics · 2025
This paper examines the concepts, technologies, and services of various types of electronic wallets and compares and analyzes their security features. Additionally, it presents specialized security threats through cases of breaches of key information that need to be managed according to the type of electronic wallet. One of the main contributions of this paper is that, unlike existing studies, it provides explanations and discussions encompassing both traditional e-wallets and cryptocurrency-based wallets. It identifies and insightfully examines the functions of electronic wallets according to the type of digital asset while also incorporating scenario-based quantitative analysis to assess how effectively certain security requirements mitigate identified risks. In particular, the classification of wallet types in this paper is based on an analysis of the existing literature that has studied the services, functionality, and security of each wallet. Through this, we suggest a future direction for universal wallets by highlighting critical security requirements that may arise when identity (ID), payment, and cryptocurrency services converge in a single interface. Rather than proposing an exhaustive universal wallet architecture, this paper focuses on key technical elements that future e-wallet environments should consider to withstand the multifaceted threat landscape posed by integrated digital asset management.
