We present a mechanism to encrypt to an arbitrary collection of identities using a variant of the Boneh-Franklin identity based encryption scheme. The decryptor is defined by a logical formulae of conjunctions and disjunctions. This enables a simple mechanism to drive access control to broadcast encrypted data using user identities as the public keys.
