Hi there!

This time, I will share with you the encryption features of WDM/OTN equipment.

The WDM/OTN devices of Huawei support port-level service encryption as well as various services and rates. The AES-256 algorithm is used to encrypt the OPUk payload.

All-service port-level encryption network:

Encryption features

Encryption features of Huawei WDM/OTN equipment:



Encryption type

Bidirectional P2P service encryption

Unidirectionally static P2P/P2MP service encryption

Dynamic multicast service encryption

Typical service type

SDH/SONET, Ethernet, OTN,   SAN, and video services

Minimum encryption unit

Board port level. Users can be allocated by port and port-specific encryption can be configured. In this way, service applications are more flexible.

Encryption algorithm

The standard AES-256   encryption algorithm in CTR mode is used, which has the highest security level.

Key algorithm

The key is dynamically generated.

Bidirectional P2P service encryption: key negotiation based on the Diffie-Hellman algorithm.

Unidirectionally static P2P/P2MP service encryption: key calculation based on the PBKDF2 algorithm.

Dynamic multicast service encryption: key calculation based on the PBKDF2 algorithm.

Key management

The public key information is stored in the OPUk overhead and   can be transparently transmitted over a third-party network.

The key change period is configurable.


The SMT and NEs   communicate with each other using the SSL/TLSv1.2 protocol, preventing   management information from being eavesdropped.


A pair of devices checks   the peer end's authentication information before starting key negotiation.

That's all, Thank you!
