Presentation by Mr. Floyd DCosta, Co-founder @Block Armour, CEO @Blockchain Worx at NUS-ISS SkillsFuture Series Seminar: How the world is experimenting with Blockchain

1. Smart City, Secure
City
Securing connected devices and critical IoT
infrastructure with Blockchain-enabled Cybersecurity
Blockchain-based digital identity for
connected devices
Tamper-proof logging of all identity
and access
Locked-down & secured access to
critical IoT systems

2 The Internet of Things connects numerous everyday devices,
opening up previously closed systems to remote access & control
The IoT market is expected to grow to an install base of 30.7 billion devices by 2020 and 75.4 billion by 2025*
Smart, connected devices are now an integral part of our lives, in business and at home

Smart homes and
offices enabled
with a host of
connected and
smart devices
Connected cars,
autonomous
trucks, unmanned
aerial vehicles,
etc

physical platforms
managing critical
infrastructure
Smart Cities with
sensors and digital
mgmt. systems for
energy, utilities,
transportation, etc

3 However, the rapidly growing world of perpetually-connected
smart devices presents proportionally large security risks
Existing security solutions are unable to keep pace, scale up and address the security challenges facing the emerging IoT world

In 2016, botnet armies DDoS attack of DNS infrastructure sent major
internet platforms and services offline
Since 2016, researchers have shown how attackers could hijack a
vehicle. In 2017, US Homeland Security cyber sleuths hacked a Boeing
757 as it sat on the runway
In 2017, criminals hacked a connected fish tank and stole data from a
casino
In late 2016, ‘Crash Override’ malware took down the power grid in Kiev,
Ukraine for over an hour before Christmas

While blockchain technology is today predominantly being used within the ‘fintech’ context , organizations - both public and private-
are starting to look at use cases beyond financial services
How a blockchain works
ImmutableCryptographically
Secure
Blockchain
Consensus

Distributed
P2P network
Secure
math-based
system
Decentralized
The first electronic value transfer protocol
A wants to send
money to B
The transaction is
represented online
as a `block’
The block is broadcast to
every party in the network
Those in the network approve
the transaction is valid
The block that can be
added to the chain, which
provides an indelible and
transparent record of
transactions
The money moves
from A to B

Key features of Blockchain technology
Blockchain technology, by its very nature, lends itself to integrated
decentralized security monitoring efforts
The blockchain, a cryptographic ledger comprising of a digital log of transactions shared across a public or
private network, can address many of the pitfalls of existing IT systems

Emerging technology offers opportunities to secure sensor networks, IoT devices and smart infrastructure in bold new ways
Decentralization
Cryptographic Encryption
Immutability
Software Defined Perimeter (SDP) architecture & Blockchain
technology provide us credible options to secure IoT Systems
Consensus-based Control
Software Defined Perimeter (SDP) Blockchain Technology
Developed at the Defense Information Systems Agency
(DISA). Used by the DHS & DoD
SDP

1. Centralized Controller
4. List of authorized
Accepting Hosts determined
5. Accept communication

Control Channel
Data Channel
6. Receive list of IP’s of
Accepting Hosts
3. Mutual secure comm. to

7. Mutual secure
comm. channels
SDP architecture render devices invisible to attackers; and customized agents along with Blockchain
technology delivers a new breed of digital identity and access control for connected devices in the IoT

6 Leveraging emerging technologies, security solutions can be
designed explicitly for connected devices and critical infrastructure
IoT Armour, for example, leverages digital signature based identity and authentication for humans,
machines and data; securing connected devices and tightly ring-fencing critical infrastructure
IoT Armour delivers an enhanced Software-Defined Perimeter using private permissioned Blockchain and TLS technology
