This Hardware Security Module Safeguards V2X Communication
The plug-and-play security solution is based on a highly secured, tamper-resistant microcontroller for securing telematics control units
Electrification, ADAS systems and rapid connectivity are driving the increased growth of communication interfaces in vehicles – whether wired or wireless. However, this development faces new challenges because the numerous communication channels create new attack surfaces, increasing the vulnerability of such systems. Therefore, it is important to provide safety to the passengers and protect their data.
Now addressing this is the latest SLS37 V2X hardware security module (HSM), a plug-and-play security solution by Infineon Technologies AG. It is based on a highly secured, tamper-resistant microcontroller that meets the security needs in vehicle-to-everything (V2X) communication applications within telematics control units. Also, the device protects the integrity and authenticity of messages, as well as, the privacy of the sender.
The SLS37 V2X HSM helps system integrators to solve the conflicting requirements of high performance and high security in a V2X environment. Therefore, the discrete HSM is focused on high-security tasks such as key storage and the generation of signatures for outgoing messages. This removes the burden of a Security Certification from the host processor, which runs the Linux operating system, from the application software as well as the less security-relevant but performance-hungry verification of incoming messages.
Besides securing automotive telematics control units, the target applications of the SLS37 V2X HSM are roadside units or other infrastructure for V2X communication. The solution supports all major vehicle credential management systems including SCMS, CCMS and ESPS. It accepts a wide supply voltage range from 1.6 to 3.6 V, comes with a high-speed SPI interface with up to 10 MHz and is qualified for harsh automotive applications according to AEC-Q100.
Infineon’s complementary host software package makes the SLS37 V2X HSM a plug-and-play solution. Rooted in hardware and embedded in a secured and certified manufacturing environment, the personalisation concept that leverages a set of chip-unique and customer-individual certificates minimises customers efforts for key management while offering maximum security during the product lifecycle. It also eases the enabling of vendor verification, pairing and transport protection as well as secured-in-field updates.
As a discrete security controller, SLS37 provides scalability for platform development across different regions with different security requirements.
The SLS37 V2X HSM complies with the Common Criteria EAL4+ certification and can be ordered now from Infineon Technologies.
