研究目的
Investigating the development of a secure IoT-based healthcare system utilizing body sensor networks (BSN) to ensure transmission confidentiality and entity authentication among smart objects, the local processing unit, and the backend BSN server.
研究成果
The proposed IoT-based healthcare system with body sensor networks is practical and feasible, offering robust security density and user-acceptable computation costs. The system's efficiency can be further improved by optimizing the crypto-hash-modules used.
研究不足
The computation cost is dominated by the SHA-3 operations, which could be improved by replacing them with traditional SHA-family techniques. The system's scalability and dynamic configuration issues are not fully addressed.
