On the Internet of Things, Blockchain Technology for Supply Chain Management (IoT)

Algorithm 1

Context-based Merkle tree (CBMT).

Input: patient record z_i; patient public key Pa_k;

   patient private key Pk_s; Doctor keys po_d, po_ds;

   i_n nonce; st_ir temporal shadow; this Temporal Hash Signature (THS);

   height of the tree l_i; sub activity hash value i_s; p_romote sub activity root

   value;

Output: Transaction deployed in the blockchain

Begin:

  Step1: for (i1; i < n; i++)

    p_iSig((ps_dk) encrypt(rec_i,pk_pk)) //Doctor encrypt the record p_i r_ihash(p_i)

  Step 2: ts_ihash( t_i&&n_i&&p_rooti) //Registry server receives the hash

    of records and forwards it to the linker server.

    y_ihash( s_i&&ts_i&&l_i )

General ledger z_ihash( r_i&&ts_i&&l_i )

  Step 1: Linker convert the hash of value into trees and forward to the

 next higher-level server

    z_ihash( r_i && ts_i && l_i )

  Step 4: Root hash value stored in the Calendar database.

    calZ_root

  Step 5: The patient set access privilege in the Smart Contract.

  Step 6: The bytecode of a Smart Contract deployed in the blockchain.

  Step 7: Finally it is stored in the blockchain, and the signature token sent

     patient -> ths_i

     End for
