| SESSION 1: Latest advances in X.509 from organizations across the world
Recommendation ITU-T X.509 is a common standard developed jointly by ISO/IEC JTC 1 and ITU since the early 1980s. It defines frameworks for public-key infrastructure (PKI) and privilege management infrastructure (PMI) which are used as the foundation for secure transactions in business-to-business (B2B), business-to-customer (B2C) and government-to-citizen (G2C) environments. This session focused on discussing the latest advances in X.509 activities and quantum information technologies from organizations and groups globally. Moderator: Zhiyuan Hu, Director, Security Research, vivo Mobile Communication Co.
