 note = {In this paper, we present an attribute-based encryption scheme from lattices called Group Oriented Attribute-Based Encryption Scheme (GO-ABE), which facilitates users from the same group to pool their attributes to match the decryption policy of a given ciphertext. This scheme is applicable when no single user can read the message as he fails to satisfy the given policy. The idea is first presented by Li et al. in NSS 2015. However, their scheme is not secure once the quantum computers become a reality as their construction is based on bilinear mappings. To ensure the security of the scheme against quantum computers, we construct the scheme using lattices.},
