Perform a structured threat model analysis using the STRIDE methodology on a hypothetical Smart Medical Inhaler. The device connects to Wi-Fi, syncs dosage data to a cloud API, and allows remote prescription updates by doctors via a mobile app. Identify potential threats for each element of STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege). For each identified threat, propose a specific mitigation strategy involving cryptography, authentication protocols, or physical hardware security measures.
