The French navy and air force are adding new encryption technology to their identification friend-or-foe (IFF) systems to reduce the chance of enemy interception and analysis. The new encryption is being applied to more than 1,000 IFF systems equipping the two services. The equipment will help ensure that links between aircraft transponders and ground-based interrogators are not read or corrupted by new interception technologies now appearing in the battlespace. The existing IFF systems receiving the encryption upgrades will be able to respond quickly and reliably in an electronic warfighting environment, company officials say. The French government has awarded a 30 million contract to EADS Defense and Security for the new IFF encryption suite.
