Device-to-Device (D2D) is a major part of 5G that will facilitate deployments with extended coverage where devices can act as users or relays. These relays normally act as decode and forward relays (semi-intelligent devices) with limited computational and storage capabilities. However, introducing such a technology, where users can act as relays, presents a wide range of security threats, in particular, rogue relay devices or man in the middle attacks (M-I-T-M). Second, passing fewer control messages is always advisable when considering authenticity and secrecy. To mitigate M-I-T-M and to reduce communication costs, this paper presents a lightweight elliptic-ElGamal-based authentication scheme using PKI (FHEEP) in D2D communication. Pollard’s rho and Baby Step, Giant Step (BSGS) methods are used to evaluate the authenticity and secrecy of our proposed scheme. The communication cost is calculated based on the comparative analysis indicating that our proposed scheme outperforms the baseline protocol. The proposed scheme can be used for any infrastructure architecture that will enhance the security of any D2D settings with better performance.

Livestock provides the motive power sustaining the life of local population and small scale industries in Pakistan. Obtaining meat and milk from sheep for the human consumption and by-products such as skins, wool, hair for local use and plays key role for the economical stability and growth of the country. There is massive amount of wool sheared by local peoples in Baluchistan but due to lack of education and technical knowledge regarding the wool shearing have remained as major issue. Shearing is made on annual or biannually, but even needs certain expertise and professionalism in the sorting of wool. The textile industry of country has greater challenge for last few decades. Government needs to upgrade vocational and technical education as well as the new equipments and machinery for wool processing in the region. Several initiatives are also being carried by small and medium enterprise for the economical uplift of region particularly and country in general. Mostly obtained wool from various regions remained as major issue for its sorting and processing for finished textiles.
