The
AIS broadcasting standard is excellent
for information sharing between commercial
ships at sea and between ships and shore
stations. This open information sharing
is however not suitable for users like
Navy, Coast Guard, Police, etc., who
have a need to exchange secure information
between their own assets and still be
able to receive the open AIS information.
Saab TransponderTech has developed the
Secure AIS solution, which satisfies
these requirements. The Secure AIS functionality
has been developed concurrently for
the R4S Secure Shipborne AIS transponder,
the R4AS Secure Airborne AIS transponder,
the Saab R40S Secure Base Station, the
Saab AIS network infrastructure and
presentation systems, in order to create
a complete solution. |
Upgrade
options are available for existing, qualified
users of Saab TransponderTech AIS products
and systems.
Crypto
solutions
Saab TransponderTech Secure AIS products
will be supplied with a built-in crypto
function with unique crypto keys for
each organization. Other schemes for
crypto key handling and encryption algorithms,
as well as external crypto solutions,
can be implemented as an option.
Qualified users
The Secure AIS solution products and
upgrades will be strictly controlled
and will only be licensed to organizations
that can be approved by the relevant
authorities in their country. A crypto
key scheme is used that ensures that
the Secure AIS functionality is only
available in those transponder units
that have a valid license for the Secure
AIS functionality. |

Secure
Link
The user defines one or several radio
channels, here called Secure Link, for
exchange of encrypted messages between
participating units within the organization.
The Secure Link is a VHF frequency,
tunable by the AIS transponder and under
control of the user. Government approval
may be required for the selected frequency.
The Secure AIS concept is an add-on
solution which will work with existing
Saab AIS equipment. The Secure AIS concept
provides a service throughout the AIS
infrastructure, enabling secure transmissions
from Control Centre operator to ships,
ship to aircrafts, etc.
WAIS
Special versions of the R4 AIS, including
Warship AIS (WAIS) functions, can be
offered to navy customers. |
