Abstract: Nowadays, keyless entry systems are widely adopted
for vehicle immobilizer systems due to both advantages of security and
convenience. Keyless entry systems could overcome brute-force key
guessing attack, statistics attack and masquerade attack, however,
they can't prevent from thieves stealing behavior. In this paper, we
proposed a new architecture try to improve the existent flaws. The
integration of the keyless entry system and the fingerprint
identification technology is more suitable to implement on the
portable transponder to achieve higher security needs. We also adopt
and modify AES security protocol for life expectancy and security of
the portable transponder. In addition, the identification of a driver's
fingerprint makes the service of automatic reinstatement of a driver's
preferences become possible. Our design can satisfy not only the three
kinds of previous illegal attacks, but also the stealing situation.
Furthermore, many practical factors, such as costs, life expectancy and
performance, have been well considered in the design of portable
transponder.
Abstract: In this paper we discuss on the security module for the
car appliances to prevent stealing and illegal use on other cars. We
proposed an open structure including authentication and encryption by
embed a security module in each to protect car appliances. Illegal
moving and use a car appliance with the security module without
permission will lead the appliance to useless. This paper also presents
the component identification and deal with relevant procedures. It is at
low cost to recover from destroys by the burglar. Expect this paper to
offer the new business opportunity to the automotive and technology
industry.
Abstract: Dedicated Short Range Communication (DSRC) is a
key enabling technology for the next generation of
communication-based safety applications. One of the important
problems for DSRC deployment is maintaining high performance
under heavy channel load. Many studies focus on congestion control
mechanisms for simulating hundreds of physical radios deployed on
vehicles. The U.S. department of transportation-s (DOT) Intelligent
Transportation Systems (ITS) division has a plan to chosen prototype
on-board devices capable of transmitting basic “Here I am" safety
messages to other vehicles. The devices will be used in an IntelliDrive
safety pilot deployment of up to 3,000 vehicles. It is hard to log the
information of 3,000 vehicles. In this paper we present the designs and
issues related to the DSRC Radio Testbed under heavy channel load.
The details not only include the architecture of DSRC Radio Testbed,
but also describe how the Radio Interfere System is used to help for
emulating the congestion radio environment.
