Using identity-based cryptography in mobile applications

TL;DR

This paper reviews case studies of mobile applications using Identity-Based Cryptography (IBC) and proposes a new scheme combining IBC with NFC for secure peer-to-peer communication, aiming to enhance mobile security.

Contribution

It introduces a novel approach integrating IBC with NFC technology for secure mobile communication, with ongoing prototype development.

Findings

Reviewed two case studies of IBC in mobile apps

Proposed a new IBC-NFC communication scheme

Prototype implementation is in progress

Abstract

This work includes a review of two cases study of mobile applications that use Identity-Based Cryptography (IBC) to protect communications. It also describes a proposal of a new mobile application that combines the use of IBC for Wi-Fi or Bluetooth communication between smartphones, with the promising Near Field Communication (NFC) technology for secure authentication. The proposed scheme involves NFC pairing to establish as public key a piece of information linked to the device, such as the phone number, so that this information is then used in an IBC scheme for peer-to-peer communication. This is a work in progress, so the implementation of a prototype based on smartphones is still being improved.
