  • Secure Boot and Image Authentication - Qualcomm
    Since the time required to verify an image is dominated by checking the segment hash values against the hash table, the addition of the Qualcomm Technologies certificate chain and signature to an image does not significantly increase the time required to verify the image
  • Secure Boot and Image Authentication - DeepWiki
    Primary Boot Loader (PBL): The root of trust, hardcoded in the SoC ROM It initializes the minimum hardware and verifies the signature of the Secondary Boot Loader (SBL1) or the Firehose programmer using a public key hash stored in hardware fuses (eFuse)
  • Secure Boot and Image Authentication Technical Overview v2 0
    Unlike earlier versions of QTI’s secure boot feature, the image metadata is contained in a separate region of the hash segment, rather than being encoded in the X509 certificate chain
  • GitHub - msm8916-mainline qtestsign: Simple tool to sign ELF Qualcomm . . .
    Supported chipsets qtestsign should work for most Qualcomm chipsets, assuming the device has firmware secure boot disabled However, the format of the hash segment changes occasionally and different firmware versions may have varying requirements for the signed images
  • Secure Boot and Firmware Authentication Policies in SoCs
    We formalize a threat model spanning supply-chain tampering, rollback, fault injection, and key-material exposure, and derive policy objectives for root-of-trust (RoT) instantiation,
  • Exploiting Qualcomm Secureboot and EDL - hyeondg. org
    Secure Boot is a foundational security mechanism ensuring that only verified, authorized software executes during a device’s boot process It establishes a cryptographical certificate chain of trust that begins in read-only-memory (ROM) and extends through each software layer
  • Analysis of Qualcomm Secure Boot Chains - Quarkslabs blog
    As it has to be implicitely trusted, a hash of its public key is stored in hardware (most of the time, in fuses), to ensure it has not been tampered with This certificate can sign another certificate (and so on ), or directly authenticate a signature
  • Qualcomm Secure Boot | Security Architecture on SoC
    Being a bootstrap sequence, each loaded image verifies the authenticity of the next image, starting from the ROM software burned into fabric of the chip However, image authentication is only one part of secure boot, and the correct setup of the runtime matters as well
  • Secure Boot and Image Authentication - Qualcomm
    Since the time required to verify an image is dominated by checking the values in the hash table, the addition of the QTI certificate chain and signature to an image does not significantly increase the time required to verify the image
  • Secure-Boot-Image-Authentication_11 - Qualcomm
    This stored Root CA hash value is provisioned to the device by the OEM, giving them full control of the device’s cryptographic root of trust The certificate chain hierarchy is shown in Figure 3 and later described in more detail
