The new Nokia DWSx (Nokia Dispatcher Workstation Generation X) enables the dispatching of secret field operations. Nokia DWSx allows the use of end-to-end encrypted (e2ee) radio terminals in the full extent of the Nokia TETRA System. Using the air interface encryption (AIE) provides high level security against external threats. In addition to AIE some user groups may require ultimate secrecy provided by end-to-end encryption. It offers protection also against internal threats within the network at base station sites, transmission lines, and switching sites. Earlier e2ee communication has been possible only between radio terminals.
DWSx completes Nokia TETRA Virtual Private Network solution
Nokia's VPN (Virtual Private Network) solution already offers innovative methods to prevent classified information leaking into other organisations. These include access right profiles based on organisation blocks and separating subscriber and group management facilities into organisations' own dedicated dispatcher stations. DWSx completes the solution with e2ee by addressing one of the main challenges of VPNs - to guarantee privacy and secrecy. For example, special police or military organisations have thus far been reluctant to share a network with other organisations.
DWSx masters the algorithms
Nokia DWSx can be delivered with a TETRA MoU recommended IDEA* based encryption algorithm or, if necessary, adapted into a national encryption scheme. High-level security can be built by using generally known algorithms such as IDEA quickly and cost effectively. Using a secret national encryption algorithm may provide even higher security. National customisation requires local implementation of the algorithm on top of Generic Encryption Interface (GEI) provided by DWSx. Similarly the same adaptation have to take place for the key management tools and the selected radio terminals.
Nokia DWSx supports both e2ee and clear mode communication since typically only part of the radio terminals use e2ee mode. There are several additional security features in DWSx including automatic and manual key flush operations to erase encryption keys from DWSx and smartcard based access control to protect the unauthorized use of the workstation. DWSx uses the same graphical DWS user interface as all other Nokia dispatcher products. This makes it familiar and easy to use and means that the dispatcher has no need for additional training when moving from one Nokia dispatcher station to another. Nokia DWSx can be connected to the Nokia TETRA infrastructure by either an ISDN subscriber line or E1 2Mbit/s connection. Different connection modes enable optimisation of transmission costs for each DWSx installation.
Nokia has a proven track record in delivering multiswitch TETRA networks capable of providing all TETRA services uniformly countrywide. The open interfaces of Nokia TETRA solutions enable seamless integration to command and control systems.
