Research ArticleOpen accessIn the keywordsA Secure Unicast/Multicast Authentication and Key Distribution Protocols for Smart GridSamah Mohamed Sayed, Heba Kamal Aslan, Ayman Mohamed HassanThis study discusses the problem of key distribution protocol in IoT systems especially smart grids for two modes of communication: Unicast and multicast. In the present paper, we suggested two protocols for key distribution for both unicast and multicast communication. The proposed schemes are based on symmetric key encryption with cryptographic primitives: Hashes and nonces. In addition, the multicast key … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 4 Jan 2023 · 5,424 accessesView PDF Cite
