IoT and Security : an impossible union ?

One of the most crucial questions to ask about the Internet of Things today is : does the IoT have a future despite its inherent lack of security ? Studies show that despite the obvious acknowledgment that this ecosystem is full of security breaches that can endanger its functioning, companies' interest in IoT does not go away.

Potentially long running operations such as network or database operations, or computationally expensive calculations such as resizing…
