Stop telling me Sigfox is clear payload, for real you’re just lazy ;)

The usual attack on Sigfox network is related to the “security”. Behind this large concept, for real, the only point is related to the use of clear payload over the air.

So saying the Sigfox is not proposing payload encryption is wrong and this option is also fixing any 6 months later message replay. It’s like saying WiFi is  not secured because you can create an open-network.

So now, let’s see why encryption is not the default option, why a network encryption standard is not the best option and then see how to stop to be a lazy developer and make encryption working.
