INTEGRITY Security Services (ISS) and Unex Collaborate to Deliver Secure SCMS V2X Communications for Smart Infrastructure and Connected Vehicles

Unex, a leading provider of SCMS V2X (Vehicle-to-Everything) systems, and INTEGRITY Security Services (ISS), an embedded security solution expert, a wholly owned subsidiary of Green Hills Software LLC., have announced a new partnership in an effort to advance safer and smarter transportation. The partnership focus on ensuring all vehicles and roadside equipment can reliably exchange authenticated messages.

SCMS V2X is emerging as a key component in the rapid rise of connected and autonomous vehicles. Exchange of information and communication between vehicles and roadside infrastructure is the basis of smart traffic and transport systems. However, similar to other wireless technology, security issues are primary concerns in SCMS V2X. For example, hackers may tamper or send fake messages. Such attacks include fake red-light violation and traffic chaos attack, which might lead to traffic accident and traffic jam.

Secure SCMS V2X communications require the technology of digital signatures including Public Key Infrastructure (PKI) service for issuing certificates and credential management services of end entity for signing and verifying signatures. Signatures and certificates ensure the integrity of message content and authenticate the identity of the senders. The ISS Security Credential Management System (SCMS) for securely delivering SCMS V2X and SCMS C2X digital certificates is the only SCMS purpose built to be secure and scale to meet the needs of today’s largest transportation fleets, networks & eco-systems. The ISS product name for their SCMS is the Security Credential Management Service (SCMS) and it was designed to meet the latest Government and Industry standards, delivering vehicle-to-anything (SCMS V2X) and European car-to-anything (SCMS C2X) certificates to automotive and smart city product manufacturers and operators worldwide. ISS raised the first and to date only North American Root Certificate ensuring interoperability and security across any vehicle or device provisioned by the ISS SCMS.

Unex’s builds a highly integrated SCMS V2X ecosystem from modules to on-board unit and roadside unit systems. Moreover, Unex SCMS V2Xcast® technology shortens development cycle for accelerated SCMS V2X deployment globally, greatly reduce the barriers to entry for all industries. To ensure the integrity and safety of communications, Unex have teamed up with ISS to mitigate any privacy risks. With ISS Security Credentials Management System (SCMS), SCMS V2Xcast® is able to manage bootstrapping, enrolment and acquisition of certificates and send protected messages.

SCMS V2X continues to thrive, delivering huge benefits to road users. Infrastructure-to-vehicle communication such as Work Zone Warning (WZW) informs drivers of upcoming events. Forward Collision Warning (FCW) warns drivers of imminent collision. “Unex’s product lineup and SCMS V2Xcast software stack enable a range of SCMS V2X applications. ISS’s expertise in SCMS V2X PKI benefits Unex to deliver secure, reliable, two-way authenticated messages among vehicles and roadside equipment. With this partnership, we look forward to a more sustainable, safer and smarter urban mobility.” said JY Ou, Unex VP R&D.

“As an ISS SCMS Certified Partner UNEX is ensuring their product’s security and interoperability in any SCMS V2X and SCMS C2X network.” said David Sequino, ISS Co-Founder & President. Sequino went on to say; “This partnership provides pre-integrated, secure intelligent transportation elements allowing for safer, smarter urban mobility networks.”
