Abstract:
System and method for establishing secure conference calls. In one example system, a central conference call server establishes point-to-point connections with accessory devices comprising a secure element and connected to corresponding participant devices. The conference call server includes an interface to a plurality of secure elements configured to perform scrambling and unscrambling of media signals communicated to and from the accessory devices. In another example, one of the participant devices operates as the central conference call server. In other examples, participant devices communicate on a conference call via point-to-point connections between all accessory devices connected to the participant devices. The accessory devices include secure elements for decryption and encryption of media signals communicated between the accessory devices.

Claim (Index 10):
A conference-call server comprising:\n a communication interface configured to communicate, during a conference-call session, a plurality of data packets to a plurality of remote endpoints of the conference-call session; a cryptographic interface coupled to the communication interface, the cryptographic interface comprising a plurality of individual physical-connection ports, each connected to a secure hardware element associated with the conference-call server, the cryptographic interface configured to receive the respective data packets sent from the respective remote endpoints and to relay the respective data packets to the respective secure hardware elements; each secure hardware element configured to:\n establish a cryptographic relationship between each of the secure hardware elements and the respective remote endpoint at least in part by negotiating respective cryptographic key information with the respective remote endpoint; and \n decrypt an encrypted packet payload of each relayed data packet; and \n an audio mixer configured to mix decrypted audio from each decrypted packet payload to generate unencrypted mixed audio, wherein each secure hardware element is further configured to encrypt the unencrypted mixed audio, and wherein the cryptographic interface is further configured to output the encrypted mixed audio for transmission to the respective remote endpoint.
