The notion of Attribute-Based Encryption (ABE) was proposed as an economical alternative to public-key infrastructures. ABE is also a useful building block in various cryptographic primitives such as searchable encryption. For ABE, it is not realistic to trust a single authority to monitor all attributes and hence distributing control over many attribute-authorities is desirable. A multi-authority ABE scheme can be realized with a trusted Central Authority (CA) which issues part of the decryption key according to a user's Global IDentifier (GID).
