As objects connected to the Internet multiply, it is likely that the stateless IPv6 autoconfiguration service will finally be used
on a large scale. Autoconfiguration aims to reduce the efforts of integrating machines into the local network to connect them to
the internet. It is based on the mechanism of neighbour discovery (NDP: Neighbour Discovery Protocol) and does not require any
administrative management of the assigned addresses. In this sense, one of the methods used to generate an IPv6 address is based
on the physical address of the machine. However, this has resulted in privacy issues for many users. The latter are concerned that it
is possible to go back to the physical computer by analysing the packets. Several approaches are proposed in the literature. In this
paper, we propose a new mechanism for generating an IPv6 address using ID tag RFID. The results of our method show the better
performance in terms of time complexity.
