• 論文抄録 / 内容記述: This paper presents the lattice-based construction of group-oriented attribute-based encryption (GO-ABE). The GO-ABE scheme facilitates users from the same group to pool their attributes to match a given ciphertext's decryption policy while securing their associated private keys. The idea of GO-ABE was first presented by Li et al. in NSS 2015. However, their scheme is not secure against quantum attacks as their scheme's construction is based on bilinear mappings. Ensuring the scheme's security against quantum computers, we construct the scheme using the post-quantum cryptographic primitive lattices and employ Shamir's secret sharing scheme to satisfy GO-ABE requirements.
