Zero-Knowledge Arguments for Matrix-Vector Relations and Lattice-Based Group Encryption

Explore zero-knowledge arguments for matrix-vector relations and lattice-based group encryption in this Asiacrypt 2016 conference talk. Delve into the work of Benoît Libert, San Ling, Fabrice Mouhartem, Khoa Nguyen, and Huaxiong Wang as they discuss Group Encryption KTY, previous works on group encryption, and the world of lattice-based cryptography. Learn about lattice-based group signatures, Stern's ideas, and techniques for dealing with quadratic relations. Understand how these concepts come together to form a comprehensive approach to matrix-vector relations and group encryption in the context of lattice-based cryptography.
