Application of MizarU Products

The Mizar product can provide high-performance hardware acceleration capabilities for message authentication required by connected car applications from the vehicle end to the cloud. Meanwhile, as a security chip, it can offer storage for critical secret data such as private keys and root certificate chains. The security chip product is equipped with SDIO, SPI, and I2C interfaces for data interaction with the host computer. The host computer can perform various cryptographic operations, key generation, key storage and management, true random number generation, and other operations by calling the chip's interfaces, thereby realizing various security function services required by the host computer applications.

Core advantages of the plan

- Secure storage: International EAL5+ and AEC-Q100 automotive certifications, with encrypted storage to ensure the security of key storage.

- Secure keys: Keys are generated using true random numbers to ensure their randomness and eliminate the hidden danger of weak keys.

- Secure connection: Key-related operations are performed inside the chip to prevent the risk of key leakage.

- Secure operation: A secure OS platform ensures that the usage permissions of all keys are safely controllable.

- Secure communication: Supports GP standard communication security for vehicle-machine interconnection.

- Secure applications: Supports international and national cryptographic algorithms as well as relevant international and domestic specifications to ensure information security in multiple scenarios.
