UCL SECReT Industry Engagement Day
Scenario
• A terrorist group have infiltrated a biochemical laboratory
•e.g. universities that have viral testing
laboratories
• Acquire a lethal virus
• Introduce into the mass public
• e.g. a large public event (Olympics)
Viral & Rickettsial Disease Laboratory, California

Access Control Security System
In our scenario the Laboratory is
protected by electronic access control
system
• RFID contactless smartcard
required for access
• Very common method of securing
building access and ticketing on
public transport e.g. UCL, Oyster.
Terrorists gain unauthorised
access to lab
• By Cloning a contactless smartcard

Sami Richardson
Access Control Security System
• MRes project – security of smartcard systems
– I plan to use Proxmark3 to
• Monitor wireless communications between smartcard and reader
• Evaluate security of system
• Reproduce known attacks e.g. how easy is it to clone a card?
– Will analyse various “Mifare” smartcard systems, including:
• “Mifare Classic”. Very insecure. Used by older Oyster cards.
• “Mifare Desfire”. Better cryptography. More secure. Now being
used for new Oyster cards.
• Security of smartcards is a possible area for PhD research next year.
• A range of possible PhD areas include:
– Computer security, networking, cryptography and telecommunications
(before UCL I was a Principal Software Engineer at Alcatel-Lucent).

Cyber Breach/Malware Detection
Possible Stuxnet Virus used to
breach computer security
• Malware injected in the months
preceding the physical attack
• Where do our computer
vulnerabilities lie, how did this
intrusion avoid detection?
Computer Security Usability
• Employees rejection of computer
security/warnings
• Employee education and awareness
of types of attack

Challenges And Advantages
• Challenges
• Detecting small targets
• Detection problems in targets at short range
• Calculating measurement parameters (Range Resolution)
• MRes Project – feasibility study using novel radar techniques to
•
to detect small target
• Advantages
• Low CAPEX and OPEX cost
• Robustness to stealth targets
• Physically small and can be deployed easily

Crossing Borders
A step ahead
• After modeling several events biolaboratory has recognized need for
assessment
• Different methods of detection using
new imaging techniques
Port Security (Airport)
• Existing security
➥ Capability of Body scanners
• Ability to integrate
➥ Optimizing (Short term)
• New solutions (Long term)
Controversial body scanner

New Solutions
Today’s research, tomorrow’s
solutions
• Range of unutilized energies
➥ THz scanning
• Depth perception (sonar)
➥ Harmless radiation (emitted by
the sun)

Gas Sensors
• Detection tool
• Mass screening of patients
– Biomarkers
– i.e. Gas in lungs due to infection of virus
• Breathalyser Device
• Gas makes contact with metal oxide
• Change in electrical conductivity signals
presence of particular gas
