You are already at the latest version IoT-connected healthcare sensor networks require authenticated and privacy-preserving data exchange among wearable sensors, mobile medical terminals, edge gateways, cloud servers, and medical institutions. Existing authentication schemes for healthcare IoT often bind signatures directly to user identities, exposing sensitive personal or institutional information and imposing heavy verification costs on resource-constrained sensing devices.

You are already at the latest version Sensor-network, Internet of Things, industrial-monitoring, and cyber-physical security graphs are increasingly outsourced to clouds, where similarity search should be supported without exposing graph content, query graphs, update contents, or database evolution. Existing privacy-preserving graph similarity schemes mainly target static encrypted databases and therefore handle insertions, deletions, label updates, and long-running index maintenance poorly.
