    Although your bank probably has a https site, it's website still is visible to everyone, yet everyone knows it's (probably) the real site.
    I know there are exceptions, and problems as well, but it's a lot safer than no encryption at all, and still readable to all, including FR24.
    The point in encryption here would be so the data is only visible to those who have need to see it.

    It's a minefield of the data is exceedingly useful to ATC and to on board systems for collision avoidance. You also need to have affordable equipment - so aircraft operators can fit it.

    If you have any system that is affordable and able manage collision avoidance, then it could be programmed to do the opposite ... encryption just adds complexity.

    On guns - no matter what the rules are - the bad boys will find a way around them.

    No, the point would be that what you get is what was intended, e.g. the info can be trusted. So only trusted parties should be able to produce the info, while everybody is able to read it.

    Unfortunately the problem with this argument is that almost everything man has ever invented can be deemed 'dangerous' or a 'threat.' Life is full of danger. (I was an electrician before retiring- crickey that stuff needs to be banned).

    Perhaps we should all go back to the dark or stone age? No, wait, they had flint and were able to produce fire- bloody dangerous stuff that.

    I've never seen such a rubbish argument in my life. We should all curl into the fetal position and crawl back into bed- we're doomed? What utter rot! Let's all give up on new technology and raise the white flag of surrender? Garbage!

    That's just my humble viewpoint. Now, back to bed and tuck my head under the pillow and hide.

    Well said. I don't think this topic serves the best interests of a community whose ongoing primary interest (after MH370 is no longer newsworthy) is plane spotting for fun and it should be terminated. Those who want to speculate are able to do so elsewhere on any number of fringe blogs.

    This is the point.

    The stated aim of the ADS-B deployment is to provide primary ATC coverage - at least in those areas that have no radar / Mode S coverage. And with this increased coverage comes with the promise increased traffic density and so on.

    But none of these gains can be realized if the system cannot be trusted. The protocol has no security at all. Attacks against ADS-B could hardly be characterized as attacks since that characterization would imply some level of difficulty.

    Rather than being an affordable system ADS-B it risks becoming a very expensive one in that the money has been spent with no real hope of achieving the goals set.
