First responder features

Configuring the MFD for First responders enables extra features that are otherwise not available on the MFD. Several of the First responder features require a STEDs compatible AIS transceiver to enable Sensitive Tactical Information Exchange and Display System (STEDS) functionality.

First responder and STEDS features require First responder to be selected as the ‘Boating activity’ during step 2 of the MFD’s initial startup wizard.

STEDS specific features also require

• an AIS5000 to be connected to the same NMEA 2000 / SeaTalkng® network as the MFD.

  Note

  The AIS5000 must be correctly configured with an MMSI number and where required a radio operators license must be obtained.

• each vessel must be configured with the same STEDS passphrase.

STEDS features use the existing Automatic Identification System (AIS) network to transmit and receive messages and data but as the messages and data are encrypted they are not visible or available to standard Class A and Class B AIS receivers/ transceivers.

STEDs encryption

The encryption is 128bit AES encryption which is compliant with the requirements of FIPS (Federal Information Processing Standard Publication). The symmetric STEDs passphrase is used to encrypt and decrypt STEDs messages to ensure that only vessels with MFDs configured with the same passphrase can send and receive the messages.

e.g. If another law enforcement geographically close to your network of vessels also uses the STEDs encrypted MFD functionality, unless they have a matching key there cannot be any interaction between the 2 agencies, and instead each agency will see the other’s vessels as a normal AIS target (providing they aren’t in AIS restricted mode).
