The SEU-8201 is a high-security
voice ciphering system which is mainly used for
commercial authorities, government agencies, police
and military organisations. The ciphering algorithm
is a new approach, providing the highest security
needed for such user groups. From a practical
standpont, it is not susceptible to attack by
eaves-droppers, etc. or by using current analytical
methods.
The SEU-8201 Voice Ciphering System
can be implemented into already existing radio
networks for end-to-end ciphering without
the necessity of changing radio communication
infrastructures. The SEU-8201 system guarantees
a secure and economic solution for high security
applications without compromise.
The SEU-8201 is compatible with complex radio
networks, such as multiple repeaters and simulcast
systems. No additional bandwith is required for
ciphering mode, and for relay operations, no special
repeater is required.
Ciphering and deciphering takes
place with essentially no delay and therefore
is not noticeable by the user.
User defined algorithms and addressing
schemes can be integrated. The length of the communication
key in conjunction with a highly sophisticated
algorithm makes it suitable for high security
tactical radio networks.
The module can be retrofitted
into most current radio sets. Modules are available
for most of the popular types of radios. The SEU-8201
can be supplied as PCB's or add-on units. A ruggedised
military version for use with AN/PRC...can also
be provided.
