Introduction
The Mobile Traffic Police Communication
Foundation
Improving Database Performance
Conclusions

I. Introduction(1)

The number of registered motor vehicles
in the world in recent years

Problem in road traffic enforcement


Limited resources of traffic police
Now traffic infraction registration

Still done manually by a pen and a notebook
3
I. Introduction(2)

Mobile telecommunication application





Using a mobile phone on network
Anywhere, anytime
Enhance the existing registration method
Central database can updated in real time
Be convenient and efficient
4
I. Introduction(3.1)

Some challenges in traffic police mobile
telecommunication:
A.
Client Devices
•
•
•
B.
Small screen
Mobile phone battery
Limited processing resources and storage space
Cellular Network
•
•
The bandwidth limitation
Vulnerable to theft and loss
5
I. Introduction(3.2)
C.
Traffic Police Data Center (TPDC)



Update real time simply
Responsibility time
Security



Client authentication
Data encryption
Integrity

II. The Mobile Traffic Police
Communication Foundation
A.

Mobile Client
SIM card acts as



A tampered resistant device
A cryptographic device
Menu-driven application


A specific PIN number activate the application
The SIMToolkit application

Packages all information into an encrypted
message and sends it to the SG between GMS

Communication Foundation
B.
Police Keys Sever

Main functionalities:
A.
B.
C.

Generation new keys
Issues Keys to the SG
Maintains a database containing the valid Keys
and Revocation Lists (CRLs).
For encryption and officer validation

Symmetric encryption algorithms
9

Communication Foundation
B.

Police Keys Sever
To reduce the risk of key transmissions

A novel methods


Changing of exclusive key two parties periodically
For security improvement

A novel protocol

Regard to


Offender driving license data in TPDC
The police officer

Encrypt the first message

Using TPDC issues the first key
Req_Verify _License  {H( IDofficer), fAES( Driving License )}

After issue traffic ticket

A new key generation



The first key from TPDC
Any predetermined date from POD
Encrypt traffic ticket and Daily_session_ID
New_Key  { Old_Key, POD} fAES

Security Gateway



The User Authentication Agent(UAA) module
The Access Point module (AP)
The Cryptographic module (CU)

III. Improving Database
Performance

Optimizing the database

Proposed Method for Database Performance
Tuning
Officer search request distributed across multiple
servers
 A dispatcher do load balancing
 Request for insert send to whole servers
 Request for search send to only one server

21
IV. Experimental Result(1)
22
V. Conclusions(1)


With growth of infraction manual method
goes to be unusable.
Police communication


Security and be quick
Anywhere, anytime
23
V. Conclusions(2)

we propose a secure traffic police data
center


Introduce our method tuning


protect and establish their communication in
authentication and confidentiality
minimize the response time
It can be extended to the other mobile
information systems
