Multicast Security for Tactical Networks (MSEC-T)

The Army has identified the need for secure IPv6 multicast to support operational synchronization through efficient bandwidth utilization in low-bandwidth tactical network environments. The current group control and key distribution schemes do not perform well in networks with limited bandwidth, longer delay and intermittent connectivity, and are susceptible to network-based attacks. In this SBIR effort, Architecture Technology Corporation (ATC) will develop an innovative technology called Multicast Security for Tactical Networks (MSEC-T) to provide secure group control and key management for multicast groups with high resilience to network variability and scalability for the tactical operational environment. A set of countermeasures will also be provided to defend against network-based attacks on IPv6 multicast, such as enemy traffic analysis and DoS attacks. The technology will be developed to operate within the existing COTS network infrastructure to provide a cost-effective solution to secure IPv6 multicast in tactical networks.
