Abstract: Disclosed herein are methods and systems for enabling legal-intercept mode for a targeted secure element. In an embodiment, a method includes embedding a first key-negotiation parameter associated with a target client device into an intercept secure encryption element; configuring an encryption-management device to receive the intercept secure encryption element and to receive a second key-negotiation parameter associated with the target client device and obtained from a service-provider system, the encryption-management device configured to embed the second key-negotiation parameter into the intercept secure encryption element; and providing the intercept secure encryption element to a communications-intercept system configured to obtain intercepted messages associated with the target client device, the intercepted messages comprising session-key-negotiation messages and associated data messages encrypted with a corresponding negotiated session key, wherein the intercept secure encryption element is configured to (i) identify the negotiated session key based on the session-key-negotiation messages and the first and second key-negotiation parameters and (ii) decrypt the data messages with the negotiated session key.

Abstract: System and method for establish 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.
