    Achieving secure multicast communication for IoT devices in Aging in Place system
    (University of New Brunswick, 2024-10) Gui, Jinkun; Lu, Rongxing
    The integration of IoT devices in Aging in Place (AiP) scenarios enhances elderly care but introduces security and privacy challenges. This thesis proposes two schemes to address these issues: an efficient multicast authenticated encryption scheme and a threshold authenticated encryption scheme. The former ensures secure and efficient communication among multiple IoT devices by utilizing Merkle Tree, prefix encoding, XOR filter, and ASCON encryption. The latter uses ElGamal threshold decryption and a binary fuse filter for secure group communication, allowing dynamic membership changes. Both schemes provide robust security, ensuring data confidentiality and integrity while being computationally efficient. These contributions enhance the security and privacy of IoT-enabled AiP systems, benefiting elderly individuals and their caregivers.
