Embedded Secure Solutions for Connected Cars

Secure elements and embedded SIMs in connected vehicles are developed to ensure the key functions that permits to fight against service and network access corruption, device cloning and counterfeiting & data eavesdropping and corruption: 

  • V2X & Cellular V2X Connectivity: thanks to eCall, Diagnostics, SW upgrade, payment & internet services, ADAS
  • In-car security communication & platform integrity
  • User data storage to prevent physical and cyber attacks, to guarantee passenger safety, vehicle behavior and data privcay

To address these challenges, ST has developed the ST33G1M2A. Based on ARM® SecurCore® SC300 32-bit RISC core, the ST33G1M2A ensures high-quality security solutions for Automotive-grade applications. 

ST33 Automotive Secure Element Solutions

ST proposes a complete offer of ST33-A for Secure Automotive including eSE and TPM solutions that are tamper resistant. 

The ST33-A TPM is based on ST's proven ST33 Secure Element hardware and a strong leadership in TPM solutions for PC and consumer sectors. In compliance with Common Criteria EAL4+, FIPS 140-2 level 2 and TCG requirements, this platform provides protection against physical and logical attacks. 

The ST33-A eSE ensures security on-board in both telematics and gateways of the automotive system. It guarantees that user data and keys are stored securely and that communications are done in a secure way. 

ST33 Automotive Connectivity Solutions

The ST33-A eSIM is a product compatible with embedded SIM solution dedicated to Automotive environments. 

The embedded SIM (eSIM), defined by the GSMA SGP02 specification, is a scalable solution that makes possible to change over the air the network providers (profile) without impacting the eSIM itself. In this case, the connectivity solution is an interoperable and flexible solution. Now, OEMs can control their car network connectivity at anytime and anywhere. 

On extreme situation, as car accident, the feature "emergency call" (eCall) is vital. In this case whom every minute counts, the ST33-A eSIM is quick on the draw to proceed this call to the authority. 

On top of that, the ST33-A eSIM perfectly support automotive environement constraints. Its AEC-Q100 certification makes it a robust and reliable product.
