| Abstract | This study offers an alternative to current implementations of key exchange by utilizing NFC technologies within android mobile devices. Supporting key exchange protocols along with cryptographic algorithms are offered, which meet current security standards whilst maintaining a short key length for optimal transfer between devices. Peer-to-peer and Host Card Emulation operational modes are observed to determine the best suited approach for key exchange. The proposed model offers end to end encryption between Client-Client as opposed to the usual Client-Server encryption offered by most Instant Messaging applications. |
