Month: 2025-12 — Wireless onboarding for cameras in rdkcentral/rdk-wifi-hal was hardened by delivering a security-focused feature and fix. Implemented Camera Onboarding Security Enhancement by updating SAE PWE to 2 for WPA3-Personal on 2G/5G interfaces, reducing onboarding risk and strengthening authentication (commit e1f6db4518e436908df497292f6bc704c9475c8c). Also resolved a critical onboarding failure with WPA3-Personal on 5 GHz across Vantiva and Sercomm platforms (RDKB-62584), increasing reliability of camera provisioning. The work demonstrates solid end-to-end validation, cross-vendor compatibility, and security-first mindset, leveraging WPA3-Personal, SAE, and 2G/5G radio interfaces.
