IntegraSec: Securing IoT with an Integrated Lightweight Privacy-Aware Publish-Subscribe Framework

Publish/subscribe(pub/sub) communication in IoT healthcare systems enables efficient and real-time dissemination of patient data, facilitating timely medical interventions and remote monitoring. Moreover, the pub/sub model has characteristics of loose coupling which could lead to security and privacy; this paper introduces a comprehensive security framework IntegraSec which integrates the lightweight design, LAA (Lightweight Authentication based on anonymity), LAC(lightweight access control), principle based on the AE(Asymmetric Encryption) based model integrated with different model such as anonymous authentication through, user registration and so on to enhance the access control and data privacy. Moreover, the proposed model secures the pub/sub model by safeguarding the content, securing the subscriber identity and publication authenticity for lightweight secure communication. Considering the lightweight approach IntegraSec improvises the overhead in terms of storage and communication.
