TSM: The “Super Butler” of the Digital Car Keys

In today’s rapidly evolving world of connected and intelligent vehicles, the car key has long transcended the limitations of a physical form. When you unlock the car door with a card/FOBKEY, when you share vehicle permissions with your family on your mobile phone, and when you start your car with your watch – behind these scenes, there is a powerful “behind-the-scenes hero” silently guarding: TSM (Trusted Service Manager) platform.

Imagine that your digital key’s entire lifecycle, from generation to use, to cancel, requires a careful and reliable steward to take care of it. This is the core mission of the TSM platform. This “butler” adopts a modular hierarchical architecture design, like a freely composable intelligent robot: when business needs change or technological updates, it can adap its capabilities while ensuring the stable operation of the system, making digital key management flexible and reliable.

Today, let’s unravel the mystery of TSM, the digital key of the car, and see how this “super butler” escorts your car digital key.

Decrypting the “butler team”

How the TSM platform performs its duties

If the TSM platform is compared to a team of efficient stewards, then each member has important responsibilities:

• Operations Management Portal: Provides an operation interface, where TSM platform operators control the overall situation

• SE Management: Provides functions such as SE registration and authentication, lifecycle state management, SE security domain management, and SE product type management, and strictly audits the identity and status of each secure element

• Application Management: Provides functions such as application registration, AID assignment, application status management, application version configuration, multi-application association, and SE adaptation to ensure the healthy operation of digital key applications.

• Security Domain Management: Provides security domain configuration (AID/SCP/PERMISSION/APPLICATION SPACE, etc.), SE adaptation, ARA-C (optional) and other management functions to build a security defense line for digital keys.

• Personalized Management: Provide functions such as application personalized data import, generation, query, and template management, creating a unique key for each user.

• GP Engine: Follow GP specifications, provide relevant APDU commands for SE content management, script generation, and management algorithm integration to ensure that all operations comply with international standards

• Key Management: Provides security functions such as key management, national secret algorithm calls, international algorithm calls, and encryption machine management to protect core security.

• Access Service: Provide access ID allocation for partners such as SEI-TSM AND SP-TSM, and system interface policy control, etc., to coordinate the smooth cooperation of all parties.

Global Pass

Standardization makes connectivity accessible

The TSM platform holds a number of “international passes” – following CCC, ICCE, ICCOA and other global mainstream car association standards. This means that no matter where you are or what equipment you use, this “butler” can smoothly connect with the global automotive ecosystem to ensure technical compatibility and safety.

Global Pass

Make digital keys smarter and more secure

Multi-device compatibility: Seamless Use Across All Scenarios

It supports wearable devices such as vehicle embedded secure elements (eSE), eSIMs, mobile phone SEs, and smartwatches, covering the full scenario requirements of smart terminals and vehicle hardware.

Protocol Mastery: Communication Without Boundaries

It supports GP specifications and SCP02/SCP03/SCP11A/SCP11C multiple secure channel protocols, making this “housekeeper” proficient in multiple “languages” to meet the management requirements of GP for secure elements.

Full Lifecycle Protection: Complete Control at Every Stage

From key download, installation, personalization, to pause/resume and even deletion, TSM provides end-to-end full lifecycle management. It is like giving the digital key “full insurance” to ensure that every link is safe and reliable, and to eliminate the security hazards of “the key is gone but the authority is still there”.

Hardware-Level Security: An Impenetrable Fortress

Based on hardware security modules (HSMs), the whole process of key generation, storage and use is isolated. This is equivalent to building a security barrier for your digital keys, which can effectively resist various physical attacks and side-channel analysis, ensuring that the keys are completely secure.

Flexible Scaling: Intelligence Adaptability on demand

Functional components are pluggable and flexibly extend new protocols and security algorithms. In the face of high concurrency scenarios, the platform supports horizontal dynamic expansion, just like a housekeeper who knows how to clone skills, Supports multiple users access at the same time, it can ensure stable and smooth services.

The future is here

The safety cornerstone of smart travel

The TSM platform of the digital key of the car is the silent and reliable guardian of the era of smart travel. It is hidden behind every convenient unlock and every secure start, building the cornerstone of trust in the digital world.

In the future, when the car evolves into the intelligent space we move in, this ultimate pursuit of safety and credibility will become more and more precious. TSM is paving a solid and reliable road to security for this future within reach.
