Those in technical roles associated with the LTE rollouts. Course participants may include network operators, vendors, service providers, application developers, management staff and engineers.

…LTE security must be understood


Long Term Evolution (LTE) mobile infrastructure is now being deployed. LTE introduces a new radio interface and core network architecture, which will co-exist with current 3G UMTS and GSM networks. LTE also introduces a new security architecture. This one day course outlines the technical details of LTE security, and shows how it will interwork with existing mobile security infrastructure.

The course begins with an overview of GSM and 3G UMTS security mechanisms. LTE security requirements are then outlined, followed by an overview of LTE key management authentication and encryption procedures. LTE security operations are then reviewed, including signalling plane, user plane, base station security, handover procedures and UMTS/GSM interworking. The course concludes with an overview of IMS and LTE voice security mechanisms.
