In this thesis, we have a tendency to address a brand new security drawback within the realm of collaborating device networks. By collaborating device networks, we have a tendency to discuss with the networks of device networks collaborating on a mission, with every device network is severally closely-held and operated by separate entities. Such networks square measure sensible wherever variety of freelance entities will deploy their own device networks in multi-national, commercial, and environmental situations, and a few of those networks can integrate complementary functionalities for a mission. Within the state of affairs, we have a tendency to address associate degree authentication drawback whereby the goal is for the Operator Oi of device Network Si to properly confirm the quantity of active sensors in Network Si. Such a retardant is difficult in collaborating device networks wherever different device networks, despite showing associate degree intent to collaborate, might not be fully trustworthy and will compromise the authentication method. We have a tendency to propose 2 authentication protocols to deal with this drawback. Our protocols place confidence in Physically Unclonable Functions, that square measure a hardware based mostly authentication primitive exploiting inherent randomness in circuit fabrication. Our protocols square measure light-weight, energy economical, and extremely secure against variety of attacks. To the simplest of our information, ours is that the 1st to addresses a sensible security drawback in collaborating device networks.
