Security aspects shall be considered as an inevitable part of every modern telecommunication technology.

Fillabs is actively participating in development of harmonized standards for the ITS security communication.

There are a lot of applications in transportation systems and especially in vehicles, requiring communication between different components: the communication between vehicles (V2V), between cars and infrastructure services (V2I and I2V), between cars and charging stations (V2G), internal car communications. New generation of car is going to provide new services, such as Adaptive Cruise Control, Self-Driving systems, etc. All these kinds of communication needs to be protected against various types of attack. It can be achieved using ITS Security protocol, which is able to provide a trusted channel between all communication nodes.

Being deeply involved in ITS standardization process, Fillabs takes an active part in development of the ITS Security communication protocols standards, such as:
• ETSI TS 103 097 ITS Security header and certificate formats
• ETSI TS 102 940 ITS communications security architecture and security management
• ETSI TS 102 941 ITS Security Trust and Privacy Management
• ETSI TS 103 795 ITS Misbehavior reporting

Having an in-deep experience in development of test suites for various telecommunication protocols we would like to offer to our customers all our knowlege and expertise.

Our competence in TTCN-3 language permits us to write a very robust and effective tests for various test purposes.

In co-operation with the ETSI CTI, FilLabs is actively involved in development of various test suites for different telecommunication protocols, creation of TTCN-3 based Abstract Test suites, test adapters and codecs.

The library provides the security envelop to be used for the Intelligent Transport Systems (ITS) G5/C-V2X communication based on ETSI EN 302 636-4-1. The library is fully conformed to ETSI TS 103 097 v1.3.1 and higher. It also supports some features of ETSI TS 102 941 v1.4.1 (trust lists, CRL, etc.)

The library is provided as an open source project hosted on GitHub. The project was started in 2015-2016 as a validation targetfor the ETSI ITS security test suite. The library is free for non-commercial and not-for-profit use, otherwise please contact the author.

It is written in plain C in cross-platform manner and has been compiled and tested in Linux(gcc) and Windows(mingw32,cygwin and Visual C 13) environments.

It implements the plugin interface to use various crypto engines. For the moment it supports the following:

• The OpenSSL (x86[free], ARM)
• The AutoTalks Craton 2 (ARM)

The library contains a set of examples, but most of the features are implemented in the FSMsgGen - the CAM/DENM/Beacon generator.

The Javascript parser for the ITS Security certificates and messages. It supports the following elements:

• The IEEE 1609.2 certificates
• The IEEE 1609.2 messages
• The ETSI TS 102 941 trust lists and CRLs
• The ETSI TS 102 941 certificate requests

The ETSI ITS Test Suite contains abstract test suites modules for each supported protocols. These modules are implemented on TTCN-3 language and the C++ based implementation of the test adaptation layer. All modules of the test suite has been validated over multiple devices under tests during test sessions in ETSI and on Plugtest events. The full code of the test suite is available as an open source project at  ETSI forge. Please use the last released version.
