Prof. Muriel Médard is invited to give the Keynote address to the 23rd IEEE International Symposium on a World of Wireless, Mobile, and Multimedia Networks (WoWMoM 2022) in Belfast, Northern Ireland on Wednesday June 15th 9:15AM-10:00AM in the Penthouse Suite. WoWMoM 2022 takes place at the Europa Hotel (Great Victoria Street, Belfast BT2 7AP) June 14-17, and is organized by Ulster University. Prof. Médard’s talk, “Revisiting Wireless Security,” argues that heterogeneous, post-quantum network coding schemes like GRAND can provide high security by incorporating encryption into error-correcting coding directly.
