| Abstract(in English) | We construct Multi-Authority Attribute-Based Signatures (MA-ABS) based on lattices. Our scheme is the first scheme that does not use Non-Interactive Zero Knowledge proof (NIZK) and is secure under the learning with errors (LWE) assumption. The idea is based on the technique of constructing MA-ABS from Multi-Authority Attribute-Based Encryption (MA-ABE) by Okamoto and Takashima (PKC 2013) and we apply this technique to lattice-based MA-ABE of Waters et al. (TCC 2022). |
