1. A method comprising:
obtaining, by a key distribution device, information about a first endpoint device that is to connect a participant to a multimedia conference session that has at least one other participant connected thereto, wherein the information indicates that the first endpoint device supports roaming of the multimedia conference session;
providing, by the key distribution device to the first endpoint device, encryption information for encrypting content and controls for the multimedia conference session and a universally unique identifier that is associated with the first endpoint device, wherein the universally unique identifier and the encryption information has been transferred from the first endpoint device to a second endpoint device via a secure proximity pairing connection;
obtaining, by the key distribution device from the second endpoint device, the universally unique identifier and transfer information indicating that the multimedia conference session is transferred to the second endpoint device; and
associating, by the key distribution device, the second endpoint device with the universally unique identifier such that the multimedia conference session for the participant is transferred to the second endpoint device without rekeying the multimedia conference session.
