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.
