Technical Approach
Stanford
University
Stanford Security Demo:
1. Simulation of Security Algorithms on Workstations ( 3 Laptops )
2. Demonstration of Security Algorithms with wireless modems (Ricochet,
FreeWave)
3. Demonstration of Security Algorithms on PLDs (Pamette, PAM-Blox)
4. System Integration (User Level, TCP/IP, Reconfigurable Hardware)

Accomplishments
Stanford
University
Technical Progress: Security [SU]
Reconfigurable Security Algorithms:
IDEA (arithmetic intensive) Pamette implementation @ 528Mbps = 1/2Giga-bps,
3 times speedup over somewhat older ASIC "VINCI", and
50% reduction in Power, 30% reduction in MOPS/Watt.
DES (RAW benchmark) Pamette implementation +50% speed, -50% area vs. RAW.
Space-Time-Code-Diversity (~secret-sharing) has low hw complexity
>> Challenge: system integration, standards, management.
Need to test our security algorithms with real RF links
Wireless hardware (e.g. freewave.com and ricochet.com)
Testing standard protocols (e.g. TCP/IP, SLIP/PPP):
some of the tested hw requires firmware or protocol changes,
workarounds: user-level, IPv4, Ipv6, hw-level.
>>Opportunities: combining security, robustness, compression, performance

Power
DSP versus PLD
11
•
Hurry & Wait vs. Just in Time
•
Granularity of multiple DSPs
•
Power wasted by transfer of instructions
(control) from memory to the DSP vs.
PLD has more compact representation
of the control information
