Lattice-Based Group Signatures with Logarithmic Signature Size.
ADVANCES IN CRYPTOLOGY - ASIACRYPT 2013, PT II, (2013): 41-61
Group signatures are cryptographic primitives where users can anonymously sign messages in the name of a population they belong to. Gordon et al. (Asiacrypt 2010) suggested the first realization of group signatures based on lattice assumptions in the random oracle model. A significant drawback of their scheme is its linear signature size ...More
