Summary

The webinar presents a family of Authenticated Data Acquisition (ADA) protocols designed to secure time-critical communication in smart grids. The speaker, Shabnam Saderi, a PhD candidate and research assistant at the Canadian Institute for Cybersecurity, explains the vulnerabilities of traditional grid communication protocols like Modbus and DNP3, which lack built-in security. She highlights the challenges of adding security to resource-constrained devices and the strict latency requirements of protection systems. The proposed solutions include PSK-ADA and Cert-ADA, which provide authentication, integrity, confidentiality, and identity privacy. The talk also covers post-quantum variants using lattice-based cryptography to prepare for future quantum threats. Experimental evaluations compare the protocols against TLS, showing lower latency and overhead. The Q&A session addresses deployment challenges, balancing security and latency, post-quantum readiness, industry-academia collaboration, emerging threats, and future research directions.
