Intelligent Transport System (ITS) aims to achieve traffic efficiency by minimizing traffic problems. ISO/TS 21177 contains specifications for a set of ITS station security services required to ensure the authenticity of the source and integrity of information exchanged between trusted entities.
ISO/TS 21177 specifies ITS station security services for enabling trust between ITS-Station application processes running on different ITS Station Communication Units (ITS_SCUs) of the same ITS station communication, i.e. establishing a trusted processing platform, considering also trust inside an ITS-SCU protection of applications from the actions of other applications, protection of shared information, and protection of shared processing resources such as communications software and hardware, which includes methods of prioritisation and restricted access.
These ITS station security services are essential for many intelligent transport system applications and services including time-critical safety applications, automated driving, remote management of intelligent transport system stations, and roadside and infrastructure related services.
ISO/TS 21177 on ITS station security services is useful for:
ISO/TS 21177 provides you with guidelines for ITS station security services required to ensure the authenticity of the source and confidentiality and integrity of application activities taking place between trusted devices. Applying the basic security specified in ISO/TS 21177, the intelligent transport system station communications can establish secure application sessions.
These security services in ISO/TS 21177 include the basic security features of authentication and authorization, confidentiality and privacy, data integrity, non-repudiation, secure session establishment which are required to exchange information in a trusted and secure manner.
ISO/TS 21177 presents the logical architecture, which is designed to accomplish two peer ITS-station application processes can communicate securely, in an authorized, integrity protected and confidential manner.
Implementing ITS standards such as ISO/TS 21177 enriches commuters with benefits such as prior information about traffic, local convenience real-time running information, and seat availability; which reduces travel time of commuters as well as enhances their safety and comfort.
