Space-Efficient Key-Policy Attribute-Based Encryption from Lattices and Two-Dimensional Attributes
Linear secret-sharing scheme (LSSS) is a useful tool for supporting flexible access policy in building attribute-based encryption (ABE) schemes. But in lattice-based ABE constructions, there is a subtle security problem in the sense that careless usage of LSSS-based secret sharing over vectors would...
