Quantum Encryption

The most critical aspect of existing encryption solutions is the key exchange process. Traditional key distribution technologies are based on public key cryptography or manual key exchange and therefore do not provide sufficient security. The security of key distribution using quantum cryptography is guaranteed by the laws of atomic physics. Quantum key distribution is a technology that allows encrypted key exchange between two remote parties over an optical network in complete security, exploiting the principle of atomic physics that observation causes interference.

The Cerberis contact encryption device is a quantum cryptographic device capable of contact encryption without delay. It incorporates a combination of quantum key distribution (QKD) and encryption engines compliant with the Encryption and Encryption Standard (AES) in a single device. Cerberis is a transparent encryption device for Layer2 networks, providing a secure bridge between two Ethernet (IEEE 802.3u) based optical networks (up to 100km distance, which can be extended by cascading).

The QKD continuously exchanges cryptographic keys over a dedicated optical fibre.

The keys are exchanged at regular intervals, up to 100 times per second, and can be used for AES 128-bit, 192-bit, or 256-bit Layer 2 encryption devices.

Cerberis contact encryption can also be operated off-line. A web server application is also available to display system log information. On-line single point monitoring is also possible using SNMP v3. The system is compatible with all network protocols (e.g. IP, Netware IPX, AppleTalk). Cerberis devices allow remote interconnection of networks to form a single reliable network.
