Security Trusted Platform Module (TPM)


SUDI is short for Secure Unique Device Identifier. When used in conjunction with [TPM](/security-trusted-platform-module-tpm), it proves hardware origin and a hardware-derived secure boot process to prevent unauthorized code from running during the booting on a Cisco platform. The SUDI is an X.509v3 certificate that is actually stored in hardware on the device.
