   Maximum performance, security and ease of use with automated KEYNET managementand protocol-agnostic technologyCONCORD, Mass.--(Business Wire)--Technical Communications Corporation (NasdaqCM: TCCO) announces itsinteroperable family of DSD-72B-SP SONET/SDH path encryptors, providing global,strategic-level security to prevent interception of all types of communicationstransmitted over fiber optic networks, while being easy and cost-effective toimplement and manage. John Maher, director of Engineering and Product Development at TCC, said,"DSD-72B-SP encryption devices integrate seamlessly as a network overlay onexisting networks - no network modification is required, network performance isnot affected, and encryption devices are only needed at the end points of thenetwork." SDH/SONET headers are transparently processed, allowing the DSD-72B-SP tointeroperate with any standard SDH or SONET network element such asmultiplexors. Individual path virtual container data payloads are encrypted,leaving the path overhead unencrypted for unrestricted network switching of eachVC with no plaintext exposure of the path-encrypted data payload. Automated Key and Device ManagementThe DSD-72B-SP secure network is centrally deployed, configured and managed byTCC`s advanced online KEYNET Optical Manager. Network policies are supported,and automated key management, logs, alerts and polls provide trusted securecommunications. "With KEYNET, a network expert is not needed to manage network security. Thelevel of security and ease of use of KEYNET, combined with the efficiency andperformance of our protocol-agnostic technology, makes DSD-72B-SP encryption acost-effective investment," added Maher. CryptographyThe DSD-72B-SP is a FIPS 140-2 Level-3 designed, hardware-based encryptiondevice in a tamper-proof, rack-mountable appliance using three-tier symmetrickey management with AES 256-bit algorithm. National algorithms can also beintegrated without hardware modification. SpecificationsThe DSD-72B-SP is exportable and operates at either 622.08Mb/s or 155.52Mb/s,and is available in industrial, government and military variants.
