SYSTEM AND METHOD FOR SECURE MOBILE COMMUNICATION

Title:

SYSTEM AND METHOD FOR SECURE MOBILE COMMUNICATION

Document Type and Number:

WIPO Patent Application WO2002007404

Kind Code:

A3

Abstract:

This invention relates to a communication system (100) and a method of providing secure communication therefor. The communication system (100) comprises two networks (101, 129) each having a security controller (201, 203) and a network element (123, 125). The two security controllers (201, 203) are operable to negotiate a security key and a security mechanism and communicate this to the network elements (123, 125). The security mechanisms include security algorithms and protocols. The network elements (123, 125) then communicate with each other using the security key and security mechanism communicated. The communication between the network elements (123, 125) is via an Internet Protocol connection and the security mechanism and security key form a Security Association as defined in IPsec as Standardised by the Internet Engineering Task Force (IETF). The invention is applicable to UMTS communication systems.
