the wireless systems, but they still deal with some limitations. Essentially, the Blockchain has an obvious
weakness which is its access control and a lot of hard work must be put into the service in order to learn
how to manage such a risk. Also, if we talk about the IoT solutions there is the big question regarding
how well secured our endpoints are; for instance, what happens when someone gets their IP addresses
and the other access permissions. Finally, it’s well-known that any encrypted Wi-Fi connection would
deal with some access control details and from that perspective – it would not be that easy for someone
coming from the outside to intercept a signal in or close to the user’s range.
An introduction
The main fact with the wireless web is that it would deal with some encryption, but such a method of
assurance would be an end-to-end cryptography. That sort of protection could offer suitable access
control, but the signal getting transmitted through the surrounding could be easily grabbed from the air
and put through some well-planned cryptanalysis. In practice, there is a wide range of procedures and
methodologies that could be applied in order to surveill the entire network traffic. From the current point
of view, wireless communications may look like secure, but they would in fact be more vulnerable and
less responsive to cybercrime attacks.
The obvious concern with wireless networks is that anyone who wants to connect with their signal would
need to seek some kind of access to that network in order to become part of such an infrastructure. There
would be a plenty of cutting-edge wireless solutions and anyone offering something getting that brand
new would claim that his service was unbreakable. What irony – the entire researchers community would
report frequently about the successful network breaches, but the point is that we are still so far away from
being safe and secure at our spots. So, would there be anything new in case of the Blockchain
technologies? The fact is any offering on the marketplace has its pluses and minuses and maybe the
“encrypted records” technology could provide less stress, but it’s still far from perfect!
The challenges of wireless information transfer
The major challenge with the wireless information transfer is its range. It’s well known that NASA can
communicate with rovers on Mars using radio link. Some space industry projects would receive the
findings day-by-day from some systems being outside of the Solar system. On the other hand, the biggest
preoccupation with our so “on the ground” solutions is that both – Blockchain as well as IoT – have
become so dependent on web communications. In other words, those wireless technologies would
undoubtedly rely on TCP/IP channels and any device or object being the member of such a system would
get its IP address assigned there. The IP address is the number hackers would most love to get, and
once they obtain it, all our nightmares would turn into a reality. In other words, even if Wi-Fi encryption
would work well in protecting anyone getting the access to your internet traffic, the security of your end
client could remain vulnerable.
Could Blockchain channel offer a better link cryptography?
From the perspective of cyber defense, the Blockchain could be applied to the well-developed link
encryption. The entire industry 4.0 could use these solutions as a route to next-generation industrial
