Application Scenario

Application in OBD （CCM3310S-T):

Security chip in the application of OBD(On-Board Diagnostics）: 

OBD is part of the diagnosis system used for monitoring and reporting the vehicle's operational status and fault information.

CCM3310S-T provides identity authentication for devices connected to the OBD system, meanwhile performs the integrity protection and encryption/decryption of OBD data to ensure the security of sensitive data.

Application in T-BOX(CCM3310S-T):

Security chip in the application of T-BOX：

T-BOX is an onboard wireless communication module used for vehicle communication and remote control functions.

CCM3310S-T aims at secure identity verification to ensure that only authorized devices and users can communicate with the T-BOX. Moreover, it encrypts sensitive data to ensure the security of uplink and downlink data.

PEPS (CCM3310S-H):

Security chip used in PEPS application:

In the application of PEPS, the traditional physical key is replaced with wireless communication devices, including smartphones, wearables, physical keys, smart cards and etc. CCM3310S-H aims at protecting vehicle access and control, and provide secure identity authentication and data encryption/decryption. What's more, it prevents unauthorized individuals from stealing and using vehicles, along with attacks such as replay and relay attacks.

CCM3320S's Application in V2X:

Security chip as a crucial component used in V2X (Vehicle to Everything):

CCM3320S's role in the V2X application is to encompass various aspects such as secure communication between vehicles to vehicles and vehicles to infrastructure, including security and privacy protection, and secure decision-making of vehicles. These applications contribute to enhancing the security and reliability of vehicle communication, thereby promoting the development of intelligent transportation systems.

ADAS Security Application (CCM3310S-T):

Security chip used in advanced driver assistance systems (ADAS) :

CCM3310S-T can enhance the security of ADAS systems, preventing unauthorized access and external attacks, thus ensuring the key functions work well, such as vehicle identification, traffic sign recognition, collision warning and etc., thereby improving driving safety and user experience. 

Advanced security application (CCM3305S)

CCM3305S provides high-performance computing power, ensuring both the security of data and real-time transmission. This helps in building a trustworthy and secure IoV (Internet of Vehicle) environment, enhancing driving safety and user experience.
