With full compliance to the SDH/SONET standards, DSD 72A-SP (STM) SONET/SDH encryption integrates as a network overlay on existing or new networks—no network modification is required and network performance is not affected. With protocol-agnostic path encryption, DSD 72A-SP (STM) SONET/SDH encryption is only required at network end points. Individual path virtual container data payloads are encrypted, leaving path overhead in the clear for unrestricted network switching of each virtual container with no plaintext exposure of the path-encrypted payload.

Networked fiber optic lines are vulnerable to interception. Leasing commercial fiber optic circuits as part of an organization's network infrastructure potentially exposes data at repeaters, adjunct multiplexors, switches and digital cross connects. Even where network elements are under the control of the user, fiber optic lines themselves can be tapped anywhere along the path. The risk is magnified by the high volume of data on these links, making fiber optic networks a target for an adversary to attack.

DSD 72A-SP (STM) SONET/SDH encryption a FIPS 140-2 Level 3 designed, hardware-based encryption solution with full line-rate performance. All peer-to-peer communications are secured with no data bandwidth impact. DSD 72A-SP (STM) SONET/SDH encryption comes in an anti-tamper rack-mountable enclosure with physical lock, meets MIL-SPEC standards and is 19" rack mountable. Three-tier symmetric key management with lossless automated key changes and multiple independent path-dedicated data encryption engines using the AES 256-bit algorithm maximize protection. Optionally, national algorithms can be integrated without hardware modification.

DSD 72A-SP (STM) SONET/SDH encryption and its interoperable industrial and rugged industrial variants are centrally deployed, configured and managed by TCC's advanced KEYNET Optical Manager. KEYNET is a Windows 7 rack mount server with tamper-proof security vault. Multiple layers of protection secure keys at every point in their life cycle with limited human intervention.

KEYNET Optical Manager also provides user-authenticated, role-based secure device management, as well as path configuration and monitoring that supports network policies (blocked, plain, secure). With an intuitive user interface and automated polls, alarms and logs, a network expert is not needed for trusted key and device management of a large network.
