SecIC-HSM

Real time and security of encrypted computing

The improvement of vehicle networking and intelligence has put forward strict requirements for the security of E/E architecture. In order to achieve complex encryption calculation processes in communication, it is necessary to integrate Hardware Security Modules (HSM) into MCU to accelerate the hardware of encryption calculation, ensuring the real-time and security of encryption calculation.

High complexity encryption algorithm of national secret algorithm

In the requirements of relevant national standards for commercial password applications, it is recommended to use encryption algorithms such as SM2, RSA with 2048 bits or more, or SM4, AES with 128 bits or more. To meet the real-time requirements of encrypted communication, hardware encryption modules are needed to implement high complexity encryption algorithms, including national encryption algorithms.

Solution

Vehicle mounted controller HSM national secret algorithm security module

Based on years of experience in AUTOSAR and information security, HSM firmware products have been launched that provide standard interfaces for integration with AUTOSAR software and support Infineon, Mainstream chip types such as NXP.
