DICE Boot Chain Via wolfCrypt’s Minimal Binary Footprint

Device Identifier Composition Engine (DICE) represents a fairly simple approach to hardware-based device identity and secure boot. DICE creates Cryptographic Device Identities (CDIs) through a blockchain-like verification process, where each boot stage measures the next component and derives unique Compound Device Identifiers using the following formula: CDI_n = HMAC(CDI_n-1, Hash(program)) CDI_0 = UDS The formulas […]
