This article analyzes various private key backup methods with a focus on the proposed indirect-permission approach. It compares this approach against traditional methods such as paper wallets and password-protected offline backups. Through security and reliability analysis, the proposed method demonstrates a significantly lower recovery failure rate than existing strategies. The risks associated with paper wallets, which can be completely compromised if the backup gets stolen, and the vulnerabilities in password-protection due to brute force attacks and forgetfulness are highlighted. The research underscores the importance of optimizing failure rates in real-world applications.
The paper wallet local storage method poses a significant risk; if the QR code backup is lost or stolen, it directly compromises private key security, resulting in a 0.55% failure rate.
Password protection for offline backups offers encryption but faces challenges; a 40% guessing success rate on leaked passwords suggests a dangerous vulnerability, and users forgetting passwords adds to potential recovery failure.
