Unified Authentication and Access Control for Future Mobile Communication-Based Lightweight IoT Systems Using Blockchain

Algorithm 1

Process for authenticating P2P identity.

A sends connection request (ID_A, M_signed_by_A) to

B:

//B query Key_A and verify the identity of A

If (Key_A_exist_in_local)

Verify the identity of A;

Else

If (Key_A_exists_in_consensus_nodes)

Verify the identity of A;

Else

Reject the connection request of A;
