Vast amounts of data are sent through the Internet of Things (IoT) on a daily basis around the world. The publish/subscribe (pub/sub) method is effective at disseminating data that need to be efficiently and securely shared among numerous users and stakeholders. But IoT devices have limited computation, communication, and storage capabilities. Data security is a challenge, as existing pub/sub frameworks rekeying requirements require high overhead. This technology addresses the critical need for efficient key management in securing IoT pub/sub channels. It leverages secure Secret Sharing cryptographic algorithms to tackle the challenge of invalidating symmetric keys possessed by the to-be-revoked nodes.
Description
This technology, SIPCA (Secure IoT Pub/Sub Channel Access), addresses the critical need for efficient key management in securing IoT pub/sub channels. It leverages secure Secret Sharing cryptographic algorithms to tackle the challenge of invalidating symmetric keys possessed by to-be-revoked nodes. Unlike conventional methods that necessitate rekeying the entire group whenever a node is removed, SIPCA eliminates this costly process of frequent re-grouping and achieves a highly secure solution with optimal communication efficiency, addressing a significant shortcoming in current approaches. This design method ensures secure pub/sub operation key creation, assignment, and updates to allow only authorized subscribers to obtain the entitled published topic data, where each topic is fed by a collection of IoT devices. This not only enhances IoT data channel security but also streamlines access control, making it ideal for large-scale and complex information sharing among distributed organizations. SIPCA's potential extends beyond the pub/sub framework, promising even greater benefits in IoT-driven distributed information sharing applications for the general public.
