The kHSM is a hardened, tamper-resistant hardware device that secures cryptographic processes by generating, protecting, and managing keys used for encrypting and decrypting data, as well as creating digital signatures and certificates. Unlike traditional solutions where external components are added to the hardware, this solution is embedded within the processor package, integrated with the processor, and communicates only via inter-processor communication protocols, guaranteeing data security. Our product is an ideal solution for automotive applications requiring security functions such as integrity protection, immobilizers, and secure in-vehicle communication, as well as for defense industry projects where secure communication, software integrity, and unauthorized access prevention are critical. Equipped with a hardware accelerator for high-computing cryptographic operations, kHSM plays a key role in helping manufacturers achieve stringent timing standards, such as for SecOC (Secure Onboard Communication) messages on communication lines.
