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 1):
A method comprising:\n receiving, by a conference-call server, a plurality of data packets sent from each of a plurality of remote endpoints, each of the plurality of data packets being in a conference-call session; relaying each of the received data packets over a physical-connection port to a respective secure hardware element associated with the conference-call server; establishing a cryptographic relationship between each of the secure elements and each of the plurality of respective remote endpoints at least in part by negotiating respective cryptographic key information with each respective remote endpoint; decrypting an encrypted packet payload of each relayed data packet; mixing decrypted audio from each decrypted packet payload to generate unencrypted mixed audio; encrypting the unencrypted mixed audio; and outputting the encrypted mixed audio for transmission to the respective remote endpoint.
