PKI for the Connected Vehicle

ECU Identity Provisioning

Issue long-lived identity certificates to vehicle ECUs during manufacturing or over-the-air. Private keys stored in Hardware Security Modules or secure boot memory — aligned with UN R155 requirements for vehicle cybersecurity management.

V2X Certificate Management

V2X communication requires pseudonym certificates that rotate frequently. ErlySign provides the certificate issuance and lifecycle infrastructure for V2X pseudonym certificate pools — supporting IEEE 1609.2 and ETSI TS 102 941 formats.

OTA Firmware Signing

Sign ECU firmware updates delivered over-the-air. On-vehicle verification ensures only OEM-authorized firmware runs — a requirement under UN R155 CSMS provisions for OTA update integrity.

Compliance-Context Architecture

ErlySign is designed with UN R155 and ISO/SAE 21434 controls in mind — supporting the certificate management requirements within a broader CSMS framework. We help automotive teams map PKI architecture to regulatory requirements.
