Several statistics achieved to date on the Internet attacks have shown that one of the major causes for their proliferation is the scarce deployment of entity authentication mechanisms. Providing seamless support for real-time applications during the inter-domain handover procedure is one of the issues that still hinder the adoption of the network entity authentication service. In this paper, we focus on the design of a novel handover re-authentication protocol that can allow overcoming the current state. Furthermore, we also define the overall requirements for the underlying class of cryptographic methods which shall be used to implement our protocol. Thereafter, we present the preliminary results that were achieved on the re-authentication protocol validation.
