FSB Russia Certifies Rutoken Chip 3127 with Five-Year Cryptographic Key Validity

Aktiv has received an FSB Russia certificate for the embedded Rutoken Chip 3127 microcontroller under security classes KS1 and KS2. The certification followed additional research that extended the validity period of the device's private cryptographic keys to five years. The chip belongs to the Rutoken ECP 3.0 3127 product line and targets long-term cryptographic protection in servers, ATMs, workstations, tablets, biometric systems, industrial equipment, and IoT devices. It stores keys in non-extractable form, performs user and device authentication, verifies component integrity, and supports trusted boot processes by controlling executable code at each stage. Additional capabilities include data encryption, derivation of session keys, secure software updates, and protected TLS and VPN connections using the CRISP protocol that complies with GOST R 71252-2024. The chip incorporates hardware-level defenses such as voltage monitoring, protective layer detection, and dummy branch execution to counter physical tampering and side-channel attacks. Pilot deployments have already occurred, including integration into the OVISION biometric access control systems, paving the way for serial use in critical infrastructure.
