Abstract
We introduce a new variant of attribute-based encryption called Group-Oriented Attribute-Based Encryption (GO-ABE for short). In a GO-ABE scheme, each user belongs to a specific group. Users from the same group can pool their attributes and private keys to ?match? the decryption policy. That is, if the union of their attributes matches the policy, they can cooperate together to decrypt the cipher-text. But users from different groups cannot make it. We give a security model and an efficient construction of this new notion, with rigorous security and efficiency analysis.
