3. A peer has a double role; one is for a number of nodes connected in IoT system,

and 2nd is that people keep the Blockchain-DL.

4. Information of IoTsystem is saved in the distributed ledger by connected peers. A

part of information which is generated by a sensor is deposited in the Blockchain-

DL by the pair operating as a sensor thing.

5. Peers build and store keys to store data for the sensors

6. Each pair keeps their keys locally

Figure7 explains the design of our proposed Blockchain-for-IoT in a clever house.

Security Analysis for Distributed Ledger STS

For safe execution, Blockchain-STS is a SHA384 hash-based technique that involves

a single-way hash feature. In this part, we’ll see how the security of Blockchain-

STS is based on the single-way of its underlying hash algorithm being reduced.

The Blockchain-STS is made up of 4 parts. Key-generation accepts n as a protec-

tion variable and gives a key-pair (^l−1

i=0 ^{(ski, pk}i^{)) A information-hash (hm) and}

a private-key (^l−1

i=0 ^{ski) are needed to sign then its return message signature of}

m(σ ^m).
