Cypher:A Mobile Application for Hardware Enabled Root of Trust

  • Abstract:
  • We present Cypher, a lightweight mobile framework for secure peer-to-peer file transfer leveraging hybrid cryptography. By combining AES for symmetric encryption and RSA for key exchange, Cypher enables non-technical users to generate key pairs on-device, encrypt arbitrary files, and share them via Bluetooth, Wi-Fi Direct, or QR codes. Unlike existing solutions that rely on server-based key management or complex desktop tools, our mobile-first approach delivers end-to-end confidentiality without external dependencies. We evaluate Cypher’s performance on Android and iOS devices, measuring encryption/decryption throughput, key generation time, and end-to-end transfer latency. Results demonstrate that Cypher maintains sub-second encryption for files up to 10 MB and key generation within 200 ms, making it suitable for real-world usage. User studies confirm an intuitive interface and high trust perception, underscoring Cypher’s potential to democratize secure file exchange.
