The WinDSX AES-256 encryption software from DSX Access Systems contains government approved AES-256 bit encryption technology that can be implemented system-wide. Encryption capabilities are built into the software and every field controller. For example, communications to each Location in WinDSX AES-256 can optionally be encrypted with a unique encryption key assigned by the customer for communicating with that Location’s field controllers. This is but another tool for DSX Integrators in meeting government requirements and FIPS compliancy just like the recently achieved UL 1076 listing. Once purchased and enabled in the DSX Features Key, there is an Encryption Key that can be implemented to encrypt communications between the Comm Server and the Workstations. There is also an encryption key that can be implemented optionally and individually for each location. Once communication is encrypted from the Comm Server to the Master Controller, the encryption is propagated to all controllers in that location.
