What is a SMART–AKK ?
The SMART-AKK acts as a small radio transmitter which grants remote access to your vehicle using a biometric verification module and a Feistel encryption scheme.
SMART – AKK Features
Hardware
AT91EB55 Microcontroller
Biometric Verification
[ARA-ME-01]
Wireless Communication [X-Bee]
AK Vehicle Simulator (AKV)
Software
Encryption [Tiny Encryption Algorithm]
Biometric Verification
Scanning & Matching up to 120 unique fingerprints
1 Master fingerprint to erase & enroll fingerprints
Enrolled fingerprints are able to control AKV
< 3 seconds fingerprint matching
Encryption
Why Tiny Encryption Algorithm?
AKV Data Packet : bits
AKK/AKV VIN Key : bits
(used to encrypt data packet)
Example AKV Data Packet:
Simplicity
Speed
Cryptographic Strength
Software
Flow
Action Command
(32 bits)
Serial Number
Before Encryption
After Encryption
A2A74BB B
Five possible action commands (Lock/Unlock Doors, Engine On/Off, Panic)
Serial number consists of synchronized counter to prevent eavesdropping
