Abstract
Embodiments extend protocols for secure communication between two parties to allow a party to securely communicate with multiple parties using a single message. For example, the sending party can determine a unique shared secret for each recipient and encrypt data for a recipient using a session key generated from the corresponding shared secret. The encrypted data can be combined into a single message, and each recipient can decrypt only the subset of the message that it is authorized to.
