Based on information from Tianyancha, Beijing CENCHI Semiconductor Technology Co., Ltd. secured a patent for the invention titled "System-Level Chip Verification Method, Device, Chip, and Equipment for Boot Image" on October 17, 2025. The patent, bearing the number CN119830296B, was filed on December 19, 2024. This innovative patent guarantees the integrity and security of the boot image by programming a root of trust—which encompasses multiple root public keys—into the chip. Additionally, it implements a multi-tiered verification mechanism. This mechanism includes several crucial steps: matching hash values, verifying user public key signatures, confirming root public keys, and ensuring a match with the root of trust. By leveraging this technology, CENCHI chips will significantly bolster the boot security protection for intelligent cockpits and autonomous driving systems. This, in turn, will mitigate the risks associated with information leakage and device malfunctions.
