  • In [1], the authors, among other results, propose a new blind signature scheme that combines LIP with the Closest Vector Problem (CVP) and a modular version of the Short Integer Solution (SIS) problem, offering a fresh direction for lattice-based blind constructions. 

    This talk will first introduce blind signatures and LIP before covering the aforementioned scheme and discussing its security.
