SONET Encryption

Securing SONET/SDH Networks Up to 10Gbps

SONET Encryption

High Performance Security Solution Providing Seamless Integration

The SafeNet SONET Encryptor is a high performance, dedicated security solution to protect 10 Gbps and below SONET/SDH networks.  It integrates easily and transparently into SONET/SDH networks and performs at wire-speed throughput, encrypting user data with the AES-256 algorithm.

Extremely low latency makes it ideal for even the most demanding real-time, latency-sensitive network applications.

Supports Path and Line SONET/SDH Encryption

The SONET Encryptor supports both path and line SONET/SDH encryption at various rates and at distances up to 40 kilometers/24.9 miles (OC48/STM16 Encryptor) or 80 kilometers/47.9 miles (OC192/STM64 Encryptor).

For added security, each encrypted circuit uses an independent encryption key pair. In addition, section, line, and path overhead bytes can be selectively encrypted, zeroized, regenerated, or bypassed.

Centralized Management or Multiple Remote Capabilities

SONET Encryptor can be managed by SafeNet's Security Management Center (SMC) via an ethernet port or in-band on the SONET/SDH network. The SONET Encryptor can also be centrally controlled or managed across multiple remote stations with CypherManager7 using SNMPv3.
