5 IOT HEADLINES Creepy IoT teddy bear leaks >2 million parents and kids voice messages [2017] IoT gadgets flooded DNS biz Dyn to take down big name websites [2016] Hackers Remotely Kill a Jeep on the Highway With Me in It [2015]

6 SECURITY? Time to market is a higher priority 357 companies in home automation 60% submitted data 76% < 10 employees Who focuses on security?

7 SECURITY? Privacy Anonymity Liability Trust

8 MAJOR GROUPINGS OF VULNERABILITIES LAN Trust Environment Trust Weak/No Authentication App Over-Privilege

9 IOT NETWORK TV

10 IOT NETWORK Sensor TV

11 IOT NETWORK Sensor TV

12 IOT NETWORK Sensor Relay TV

13 IOT NETWORK Sensor Relay TV

14 IOT NETWORK Sensor Relay Management Cloud TV

15 IOT NETWORK Sensor Relay Management Cloud TV

16 IOT NETWORK Sensor Relay Management User Interaction Cloud TV

17 ATTACK POINTS OF BREACHES ( ) Attack Points DoS Privacy Leakage Function Control Device Control Actuator/Sensor Delegate/Relay User Interaction Point Attack Count

18 EFFECTS OF BREACHES ( ) DoS Privacy Leakage Function Control Device Control Effects Attack Count

19 GROWTH PROJECTIONS 80,000,000,000 Connected Devices Number of Connected Devices 60,000,000,000 40,000,000,000 20,000,000, Year

22 SO BLOCKCHAIN?

23 BLOCKCHAIN!= BITCOIN

24 A BLOCKCHAIN IS DISTRIBUTED LEDGER

25 A BLOCKCHAIN IS DISTRIBUTED LEDGER TRANSPARENCY

26 A BLOCKCHAIN IS DISTRIBUTED LEDGER TRANSPARENCY AUTHENTICATION

34 PROGRAMMING ON BLOCKCHAINS Platforms Ethereum, RSK Smart Contracts Not legal contracts Self executing Self enforcing Live on the blockchain Solidity

35 INDEPENDENCE CONSENSUS PROCESS

36 INDEPENDENCE CONSENSUS PROCESS

37 INDEPENDENCE CONSENSUS PROCESS

38 BLOCKCHAIN SECURITY Able to reconstruct state by itself - biggest advantage Trust is within (trustless) INDEPENDENCE Autonomous entities Fault tolerant

39 BLOCKCHAIN SECURITY Validation of proposed transactions Transactions are immutable CONSENSUS Tamper proof PROCESS

40 BETTER SECURITY ON IOT WITH BLOCKCHAIN Consortium blockchains More control as opposed to public blockchains Self enforcing smart contracts Tamperproof

41 BETTER SECURITY ON IOT WITH BLOCKCHAIN Security by design & default Verification of nodes on the network Verification of transactions

42 BETTER SECURITY ON IOT WITH BLOCKCHAIN Consensus Process: Proof of Work/ Proof of Stake Make it hard to DDOS Man-in-themiddle is obsolete

43 EXAMPLE: IOT & BLOCKCHAIN Monitoring secure assets using IOT devices Possible vulnerabilities Device impersonation Function control Doctored data

44 EXAMPLE: IOT & BLOCKCHAIN IOT device on a blockchain network Store device ID on blockchain Can function without internet Data is immutable, tamper proof, blockchain is trustless Device function is autonomous with the use of a smart contract All interested parties can verify data without need for trusted central authority

45 USING BLOCKCHAIN Sensors of today can handle software stacks Ethereum

46 CHALLENGES USING BLOCKCHAIN Still WIP Time to consensus and user experience Bitcoin takes over 2 hours Ethereum about15s Scalability A blockchain to cater to hundreds of billions of devices needs to be scalable Verifying information from outside the blockchain network

47 IOT DEVICES USING BLOCKCHAIN IRL

48 IOT DEVICES USING BLOCKCHAIN IRL Active Ingredient National & Regional Wholesalers Raw Materials Finished Drug Hospitals & Pharmacies Patients Inactive Ingredient Smaller Wholesalers

49 IOT DEVICES USING BLOCKCHAIN IRL

50 THE FUTURE IS ENDLESS Blockchain voting Sharing machinery in a community (3D printers, self driving cars) Power regulation
