ASN.1 is a fairly ubiquitous standard used in many applications from telecommunications to networking to security, etc. However, most people do not even know it exists. In a series of blog posts, we will explore application areas in which ASN.1 communications are used today. The first area we will explore is vehicle-to-everything (V2X) communications.
From Wikipedia:
"Vehicle-to-everything (V2X) is communication between a vehicle and any entity that may affect, or may be affected by, the vehicle. It is a vehicular communication system that incorporates other more specific types of communication as V2I (vehicle-to-infrastructure), V2N (vehicle-to-network), V2V (vehicle-to-vehicle), V2P (vehicle-to-pedestrian), V2D (vehicle-to-device)."
There are several V2X communication standards that make use of ASN.1 to encode and decode messages exchanged between vehicles and other road users or infrastructure. Some examples of these standards include:
IEEE 802.11p: This standard specifies a set of amendments to the IEEE 802.11 wireless LAN standard to support wireless communication between vehicles and roadside infrastructure. It uses ASN.1 to encode and decode messages related to safety, mobility, and other types of information.
3GPP LTE-V2X: This standard, also known as C-V2X (Cellular Vehicle-to-Everything), specifies a set of protocols for communication between vehicles and other road users or infrastructure using cellular networks. It makes use of ASN.1 to encode and decode messages related to safety, mobility, and other types of information.
DSRC: Dedicated Short-Range Communications (DSRC) is a wireless communication standard that is specifically designed for use in transportation applications. It uses ASN.1 to encode and decode messages related to safety, mobility, and other types of information. SAE J2735 and J2945 are DSRC-related ASN.1 standards that have been developed over the years.
ETSI ITS-G5 (Intelligent Transport Systems - 5th Generation) systems: These are a set of communication standards developed by the European Telecommunications Standards Institute (ETSI) for use in the European Union. They specify a range of protocols and technologies for communication between vehicles and other road users or infrastructure, with the goal of improving road safety and traffic efficiency. Standards include ETSI TS 102 956 which is a set of data structures and rules for representing information such as system status, configuration, and performance data, ETSI TS 102 961 for representing information such as encryption keys, certificates, and authentication data, and ETSI TS 103 097 which defines a set of data structures and rules for representing information such as location, speed, heading, and more.
These are just a few examples of the V2X standards that make use of ASN.1. Objective Systems' has developed our V2X API product which implements several of the DSRC and ETSI standards. More information on this is available at the following URL: obj-sys.com/products/v2xdll/index.php
