[EAS] This weeks IPAWS RWT

[Ed Czarnecki]

Um, well that should mean that 100% of *compliant EAS devices will not log the receipt.  Section 11.56 of the FCC's rules requires EAS Participants to "configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature."  In other words, 11.56(c) basically **requires EAS devices to check digital signatures.

Maybe this is a useful exercise in a different way.  If the below is correct , and if your EAS device IS logging the RWT in question, then it might be a very good idea to double check that digital signature validation is actually enabled on your EAS device.  

If it is not enabled, then you should enable digital signature verification.

If you're EAS device does not allow digital signature verification ... you'd better contact your respective vendor ...

        Yes, Mixed bag is the best description.
        As more reports come in, it seems we have a slight improvement from last week, in that those EAS devices set to check the digital signature of incoming CAP messages may not be logging the receipt of this week's IPAWS RWT CAP message.

        Progress, but not 100% yet. Do I hear "more tests!" ??? but it appears that FEMA is not there yet."
