Abstract

En 中文

• Proposes RLWE-based VABSE for secure, verifiable, and efficient data sharing. • Achieves verifiability of search results via lattice preimage sampling. • Enables access policies of polynomial depth via key-homomorphic evaluations. • Provides resistance against (insider) KGA via bilateral authentication. • Ensures high computational efficiency through ideal lattice design.
