Motivation: Computer Security

What hackers do:
Code understanding: to duplicate, steal ideas, prepare attacks
 Code tampering: to circumvent checks, cause attacks
 Others: data tampering, authorization attacks, bufferoverflow

I can
understand the
code
Now I can
modify the
code

Software Security/Protection
 Computer
security research
Crypto, protocols, policy, intrusion detection
 Related areas: data mining, signal processing,
networking …

 Our
approach:
How can compilers be used to protect software?
 Exploit reconfigurable (FPGA) hardware
 Tools to manage security/performance tradeoff.
 Collaboration with: Bhagi Narahari (CS)

Source code
Secure compiler
Secure executable

Biomolecular Networks

Hypoxia network
23 molecules (e.g., HIF, PH,
VHL)
 Unusual effect: sharp response
to oxygen
 Our goal: explain using
mathematical (ODE) models


Boolean network models:
