Hussein Abdulkhaleq Saleh . Develop a LAN-based Password Management System Dedicated to Android Devices and Fresh Tomato Routers. International Journal of Computer Applications. 187, 8 ( May 2025), 42-59. DOI=10.5120/ijca2025925025
Abstract
This research introduces a LAN-based password management system tailored for Android devices and FreshTomato routers, offering a secure, localized alternative to cloud-based and device-centric solutions. The system integrates an Android client application with a router-based storage server, utilizing the router’s constant availability within the local network to ensure offline accessibility and reduce dependency on external services or the device itself. Passwords are safeguarded through AES-256 encryption, SHA-512 hashing, and continuous authentication, with communication between client and server facilitated by HTTP and JSON protocols. Testing on emulators and a physical device demonstrated the system’s functionality, rapid response times, and minimal resource usage, confirming its usability and performance. However, limitations include reliance on router availability and location constraints within the LAN. This work establishes a decentralized framework for password management, enhancing user autonomy and resilience against cloud-centric threats. Future enhancements could expand compatibility with other router firmwares and incorporate recovery options.
