Abstract
In some examples, a system receives, from a sender, an access control value generated based on information of a plurality of recipients. The system sends, to the sender, a signed version of the access control value for sending by the sender to the plurality of recipients with an encrypted message. The system receives, from a first recipient a request for a key to decrypt the encrypted message, a signed access control value and recipient information for deriving the access control value. The system determines whether the first recipient is one of the plurality of recipients using the signed access control value and the recipient information.
