Core engineering and protocols for UNECE WP.29 R156 Compliance.
United Nations Economic Commission for Europe (UNECE) Regulation No. 156 mandates that automotive manufacturers establish a certified Software Update Management System (SUMS) before selling vehicles in major world markets (Europe, Japan, South Korea, and others). Unprotected or unverified software updates are strictly prohibited under penalty of vehicle registration revocation.
OTACrypt guarantees that every firmware release undergoes a certified cryptographic signing ceremony. The resulting signed manifest contains the exact cryptographic hash (SHAKE-256), version identifier, target ECU hardware revision, and dependency tree, ensuring that only verified, type-approved software can be flashed onto vehicles.
