Authentication in IoT systems are vastly insecure. Mostly the problems lies on its open ended and probable untrustworthy nodes. Also, the need for a lighter authentication mechanism will always be welcomed. The fact that IPSec limitations can also be overcome and Implementing authentication using block chain technique may give it more freedom. Please suggest your insights and ideas. Please give your insights. We can work together for a project.

Hi, @Ajay Prasad,
Of course, we can use blockchain-based authentication of IoT devices.
Authentication schemes based on the blockchain technology can provide many special features, for example:
- The signing and decryption keys stay on the device.
- The verification and encryption keys are stored on the blockchain.
- Protects against critical cyber attacks such as phishing, man-in-the-middle, replay attacks...
I think this is not feasible for all IoT devices and systems because most of these last go towards low-cost solutions.
But this does not prevent to go ahead and work on such kind of schemes because it's will be suitable for many cases and scenario in IoT...
I hope my idea to be clear and at your question range.
With regards
Otmane
Yes. We can do it for sure.
FiWare is doing it with the help of IOTA (for smart cities project).
We can implement Blockchain based identity management which is using some standard authentication service.
