Electronic Vehicle Registration
in Sao Paulo, Brazil
Technical tools in use to a controlled
and secure Mass-Implementation
Dr. Dario Sassi Thober, President / Director
Wernher von Braun Center for Advanced Research
EVR in Sao Paulo State,
Brazil Pay-per-Use concept (“Point-to-Point
System”): Several Multi-Lane Free-Flow
Portals on State Highways
Cost-effective OBU that allows
installation in up to 80% of the State’s
Fleet
Highly-secured OBU to allow Public and
Private services to grow around it
Vehicle Classification and OCR also
included (trucks / cargo represent a
significant percentage of toll-collection
events)
System developed and
implemented by Von Braun
Labs in two Sao Paulo State
Highways in a Pilot-Program
Ponto a Ponto System:
Santos Dumont Highway in
Sao Paulo State, Brazil
Multi-Lane Free-Flow Portal
based on 915MHz with
AES128 technology + OCR
Another Ponto-a-
Ponto site

the State of Sao

Free-Flow Portal

Key elements of the
Brazilian AVI
Vehicles’ Electronic ID must generate secure,
reliable information if services (public or private)
affect end-users’ bank-accounts / pre-paid credits
or legal situation
– Which technology allows secure read/write commands
under an internationally recognized standard implemented
on passive, battery-less platform – similar to 6C operations?
– Which hardware platforms are based on well-known
industrial solutions to mass-deployment?
Key elements of the
Brazilian AVI
Interoperability
– Based on International Standards (GS1/ISO18000-6C)
– Well established Physical Layer (well-know commercial
Reader hardware platforms)
Security and Cost
– Implementation on 6C standard with secure custom
commands based on AES128 mechanism
– Costs similar to 6C implementations within reach
[email protected] It’s Based on SINIAV SINIAV is the National System for Automated Vehicle Identification
(Sistema Nacional de Identificação Automática de Veículos), which is currently being implemented and deployed throughout the national territory in Brazil.
SINIAV was initiated by the Ministry of the Cities (Ministério das Cidades, MC), the Ministry of Science and Technology (Ministério da Ciência e Tecnologia, MCT), and the National Traffic Committee (Conselho Nacional De Trânsito, CONTRAN) in Brazil, based on Resolutions Nr. 212 issued on November 13, 2006, and Resolution Nr. 338 issued on December 17, 2010, by CONTRAN [RES:212:2006, RES:338:2009]. SINIAV foresees the mandatory electronic registration of all vehicles in the country, including passenger cars, trucks, motorbikes, etc. The official deployment phase of SINIAV starts on June 30, 2011, to be completed by June 30, 2014.

Implementation made by
Von Braun Labs to Sem-
Parar of a EVR+Vechicle
Class system: non
installation of any sensor
on/in the pavement

Demonstration at high-
speed that 915MHz/AES128
tags are not affected either
by other 6C Tags or 5.8GHz
Transponders in the field of
the same reader
6C Tags are easily bought in the open-
market – if those are placed in the car to
cause jamming (reader overload by
tags’ collision), only 6C tags will be
affected – those with Secure Protocol
will be read as usual

Company’s Tag
