SLS37 V2X HSM

综述

Plug & play solution for secured V2X communication

Infineon’s SLS37 V2X HSM safeguards automotive V2X (Vehicle to Everything) communication based on a tamper-resistant security controller tailored to the security needs in V2X applications within telematics control units, protecting critical assets such as the integrity and moreover authenticity of messages, as well as the privacy of the sender. This plug & play security solution offers a host of benefits to automotive OEMs, tier-1 suppliers, and software providers for the development of connected vehicles.

In a V2X application the SLS37 serves as an HSM (hardware security module) for storing private keys and handling V2X security operations attributed to the most critical assets. This includes ECC private key management (generation, derivation, deletion), ECDSA signature generation, ECIES encryption and decryption, and storage of generic data.

The hardware architecture is based on a 32-bit Arm® SecurCore® SC300 CPU with an additional high-performance cryptographic engine and a latest-generation hardware coprocessor for asymmetric cryptography. For communication to the host processor, the SLS37 uses an SPI interface with data protection.

The robust, automotive-qualified hardware comes with preprogrammed firmware, both security-certified, complemented by Infineon’s V2X host library software package for seamless integration in various host application processors. Secured firmware updates with end-to-end protection make this solution future-proof as fixes can be added in the field.

As a discrete HSM, the SLS37 is agnostic to existing or upcoming modem standards.
