Fidel Camero, director of Business Development, secure wireless & radio, at TCC, said, “The HSE 6000 headset/handset radio and telephone encryptor provides strong voice security, including cross-network conferencing, that interoperates with our military DSP 9000 radio encryption family, while meeting the portability, simplicity, flexibility and cost-efficiency requirements of public safety special operations.”

X-NCrypt Cross Network Cryptography is the revolutionary evolution in the application of TCC’s military DSP 9000 voice encryption technology. It enables end-to-end secure voice communications across and between radio and telephone networks, including conferencing, using TCC’s DSP 9000 and HSE 6000 interoperable secure radio and telephone encryption family to connect fixed-sites (land, sea and air), ground troops, public safety special operations, and commanders and government officials.

Supporting universal encryption, the DSP 9000 and HSE 6000 are cost-effective and flexible, operating with most radio makes and models, and all frequency bands, and seamlessly overlaying on existing voice networks. The HSE 6000 fits in a pocket and connects to any handheld or squad radio, and any headset/handset. It also quickly connects to corded handset telephones used with VoIP, digital and analog telephone networks.


TCC’s Enhanced Domain Transform algorithm uses a highly non-linear digital key stream generator. Algorithm customization is supported. Keys and radio interface settings are generated by TCC’s Crypto Management System, while key management is user transparent.
