Symmetric encryption

Symmetric encryption scores with top performance

If you want to encrypt large volumes of data in real time, symmetric encryption is exactly the right choice. It works with just one key for encryption and decryption - making it extremely fast, efficient and resource-saving. It comes into its own wherever data needs to be transmitted with high performance and at the same time as securely as possible. And best of all, our solution with the Nokia 1830 SMS systems is already quantum-resistant.

High confidentiality

With centralized key management via the Nokia 1830 Security Management Station (SMS), we achieve an exceptionally high level of confidentiality - controlled, scalable and reliable.

Quantum resistant

The platform is already prepared for future threats. It supports quantum-safe key distribution and can be flexibly combined with post-quantum cryptography (PQC) and quantum key distribution (QKD) - for a hybrid security architecture that grows with you.

Centralized key management

Standardized, highly scalable platform for symmetric key management - a central point of trust for your network.

Fully automated key management

Keys are created, rotated and distributed automatically - without human access, for maximum security and efficiency.

Quantum-ready

Compatibility with PQC and QKD makes your network future-proof against quantum attacks.

High reliability

In the event of network failures, Nokia 1830 SMS automatically takes over key generation and restores encryption without manual intervention.

Layer 1

Direct encryption on the optical transmission layer for DWDM systems and high-speed backbones
No protocol overheads, maximum performance and transparency for higher layers
Key rotation is "traffic hitless", i.e. without interrupting the data traffic

Layer 2

Support for MACsec and Carrier Ethernet at the data link level
Automated key management for VLANs and backhaul services - including quantum-safe keys

Layer 3

Nokia 1830 SMS can serve as a key source for IPsec or VPNs
This creates a multi-layer security architecture with end-to-end protection at the network level
