The EncryptorPak L provides secure Ethernet-to-serial and serial-to-serial communications between MTU and RTUs. The unit encrypts and tunnels serial DNP3 or Modbus data and its operation requires no change to your network or applications.

Overview ▲Top

IEEE 1711-2010 standard for cyber security of substation serial links

AES encryption, HMAC authentication
Key management (2 -level)
Modbus RTU/ASCII, DNP3
Point-to-point (P2P) & multi-drop operation
Asynchronous 300 to 115 Kbps

Plus Ethernet TCP/UDP-to-serial connections

Plus Multi-protocol support

AES (8-bit CFB) in P2P for Allen-Bradley DF-1, Bristol BSAP, Fisher ROC & more

Plus 3-in-1 software-configurable ports

RS-232/422/485 interfaces

Plus Up to 200 secure tunnels

Each tunnel has its own encryption key and protects one or group of RTUs

Plus Web interface for easy configuration & management

Access is controlled by three separate roles: admin, security officer, and operator

Benefits ▲Top

Cost-effective

No change to existing software or equipment

Improves security posture

By easily defining and deploying policy-based security across serial links

“Bump-in-the-wire” security for serial DNP3, Modbus, and others
Secures serial data over radio paths, dial-up, or leased lines
Supports mixed encrypted and clear traffic for seamless operation

Flexible configuration

Any mix or match of RS-232, RS-422, or RS-485 (2- or 4-wire) interfaces via DB-9 or terminal block
Supports point-to-point, multi-drop, radio, leased, dial-up

Conforms to NERC CIP audit logging
