Abstract
ITS aims at enhancing traffic safety, reducing congestion, increasing travel mobility, enlarging economic power and controlling efficient energy-use. Since automobile is the major mode for our travel, developing an advanced safe smart vehicle in the field of ITS is important for our society. Advanced Transportation Management System is the major sub-system of ITS. The transportation of traffic data which drivers need is the most important factor for ATMS. However, the security of data transmission has been neglected by most of people. By this reason, this project concentrates on developing a security scheme for data transmission of ATMS. The technique of cryptography would be adopted to protect the contents of data packet from masquerading, replying and tampering. How to verify the source of messages is also what we concern, message digest is a good method to implement it.
Implementing the security scheme is the final objective of this research. We should concern the performance of security and efficiency because the process of encryption and decryption would consume a lot of resource of core system. How to look after both the security and efficiency of transmission is the main problem of this project. However, we consider ATMS would become more complete and secure by solving this problem.
