Bus information system (BIS) has been developed for networking passengers with bus companies that provides public transportation services. The BIS, also denoted as BISgeneralized, supports a passenger with personalized and real time bus information services in all phases of a journey. Today’s BISgeneralized encompasses multiple technologies, including advanced visual displays, public address, emergency intercommunications, digital surveillance systems, IP networks, wireless networks, video streaming, coders, decoders and many more. These systems deliver real time bus information seamlessly on vehicles and in stations, while they are controlled and managed from a single control center. However, lots of small bus companies’ services like urban city’s bus company or small organization’s bus could not afford to operate the profound services to the passenger due to the budget of the city, which requires complicated infrastructure. To provide the BIS services with cheap cost, this paper proposes a secure urban BIS, denoted by SBISurban, based on smart devices and explains the security issues related to the system operation. The SBISurban is to reduce the cost and to ensure security and privacy from the BISgeneralized. The SBISurban is secure from various attacks, provides privacy and has good properties compared with the other systems.
