A later than expected release of a technical update to Emergency Alert System (EAS) hardware used by broadcasters has led the Federal Communications Commission to give stations more time to install the software without running afoul of its rules. Stations were to have had the update installed by Friday, Nov. 8. But the Public Safety and Homeland Security Bureau will give an extra 60 days on the clock, meaning the updates need to be in place by Jan. 7, 2020.
The software update concerns how EAS equipment validates Common Alerting Protocol (CAP)-formatted alerts which are distributed by the Federal Emergency Management Agency before they are relayed to the public. That validation process requires that a station’s equipment be configured so that any CAP-formatted alert that doesn’t include a valid digital signature is rejected. It does that by looking at the message received and the digital signature created by the certificate included in the alert. The equipment checks to be sure the certificate matches one of the trusted sources stored in the EAS unit. The pressing issue has come into play since FEMA said one of the certificates it has issued for the Integrated Public Alert and Warning System (IPAWS), that has been installed in all EAS devices, is set to expire Nov. 8.
