Abstract

This paper describes an implementation of secure RICA (Robustness, Integrity, Confidentiality and Authentication) key exchange protocol. Integrity, confidentiality and authentication are the base for secure message exchange. We propose adding robustness in order to ensure better availability of the system. Robustness of presented implementation is due to Quick Response (QR) code properties. QR codes are resistant to a certain level on errors. We used GNU¹ Privacy Guard (GnuPG or GPG), version for Windows operating system, for signing and encrypting the message, as a base for secure key exchange protocol.
