Aktiv has obtained an FSB Russia certificate for its embedded microcontroller Rutoken Chip 3127 under security classes KS1 and KS2. Following additional research, the validity period of the device's private cryptographic keys has been extended to five years.
The chip forms part of the Rutoken ECP 3.0 3127 product line and is designed for equipment that requires long-term cryptographic protection. Target platforms include servers, ATMs, workstations, tablets, biometric systems, industrial equipment, and IoT devices that must independently verify trust relationships while human operators focus on other tasks.
Rutoken Chip 3127 stores cryptographic keys in non-extractable form, authenticates users and devices, checks the integrity of system components, and enables trusted boot. At every stage it can validate executable code to prevent unauthorized modifications. The microcontroller also supports data encryption, derivation of session and derived keys, secure software updates, and protected TLS and VPN connections.
For data exchange over open channels the chip implements the CRISP protocol that complies with GOST R 71252-2024. Hardware-level protections include continuous monitoring of supply voltage and the integrity of the protective layer covering the die. Any detected physical tampering attempt triggers immediate blocking of operations. A dummy branch execution mechanism performs false commands to mask power consumption and timing information against side-channel attacks.
The company reports that Rutoken Chip 3127 has already completed pilot deployments. One project integrated the microcontroller into the OVISION biometric access control systems. Completion of the certification process is expected to enable serial production use in devices deployed within critical information infrastructure.
