Abstract
Secure wiretap support for Internet Protocol security. Specifically, one embodiment of the present invention includes a system for allowing controlled access to a networked communication. The system comprises an intermediate device that includes memory. The memory of the intermediate device is for storing a policy rule therein. The intermediate device is adapted to download the policy rules governing access to a desired location. The system further comprises a client which is coupled to the intermediate device. The client is adapted to receive the policy rule when the intermediate device downloads it to the client. As such, any communication data intended to travel between a first destination and the client is forwarded to a second destination. Therefore, the present invention provides a method and system for providing law enforcement agencies the ability to wiretap specific encrypted communications. Moreover, the present invention provides this ability while allowing the established hardware infrastructure of computer networks to remain essentially unchanged. Furthermore, the present invention does not affect the performance of the network while enabling end users to utilize any encryption algorithms for their communications. Additionally, the present invention enables encrypted communication data to remain encrypted during transmittal en route to its destination.
