Define authentication
Protects communications system against acceptance of fraudulent transmission
What are the two challenge and response code systems?
AMSL 1800 = aircraft
AMSC 1800 = ground agencies
Explain Time authentication
Used to signifiy the validitiy of statement on an unsecure net
Times are always in Zulu and includes the day
Two minute validation window
Single or multiple assests
Explain characterstics of Challenge-Response Authentication 3
Primary means of establishing identity on unsecure net
Attempts to ensure every C-R sequence is unique
Protects against replay attacks
When would you wish to authenticate? 5
Imposing or lifting emergency silence Cancelling emergency silence When ordered to do so Validate a message of operational importance When in doubt
What is a Tactical Report (TACREP) 2 points
Tactical reports given on Voice Product Net indicating the collection of tactical intelligence
Assigned an alphanumeric designatior
Awake? (SIGINT Terminology)
Land or surface emitter activity detected via communications intelligence
Active? (SIGINT Terminology)
Indicates that EW emissions are currently being detected from radar site
Down? (SIGINT Terminology)
Emissions have ceased
Asleep? (SIGINT Terminology)
No longer detecting land or surface emitter activity via communications intelligence
Rotator? (SIGINT Terminology)
Moving target indicator returns that signifies a high probability of a rotating antenna
Reported? (SIGINT Terminology)
Information provided is derived from off-board sensor
Colour? (SIGINT Terminology)
Request for information on a type (system) at stated location; implies a request for ambiguity resolution.
Tag? (SIGINT Terminology)
Response to an emitter ambiguity resolution request (colour)
What is this?
“AGENT, TACREP E-04, SIX TARGET ACQUISITION ACTIVE, BULLSEYE 2-3-5/18, FREQ XXXXX, TRACK NUMBER 13207”
TACREP
What is a Situation Report (SITREP)?
SIGINT, IMINT and MTI information on surface emitters is passed on the voice product net (VPN)
Passed 5 minute prior to the package LOWDOWN
Emitters passed using system type, digital bullseye location and operating frequency
What are the reporting priorities for a SITREP?
Air activity and location in absense of an air picture
Active/awake or previously active (within last 8 hours) strategic SAMs what were not a part of the briefed EOB
Any active or previously active/awake (within last hour) tactical SAMs
EW/GCI radars
What is this?
“AGENT, SU-27 AIRBORNE TONOPATH, TWO TRACKER ACTIVE BULLSEYE 1-2-1/20, FREQ XXXXX, TRACK NUMBER 06023; SIX AWAKE BULLSEYE 1-3-5/40, TRACK NUMBER 06004, ROLAND AWAKE BULLSEYE 1-2-5/035, TRACK NUMBER 06037; TALL KING ACTIVE BULLSEYE 0-9-0/6 FREQ XXXXX
SITREP
What is a LOWDOWN
Request to provide tactical ground information pertinent to the mission in digital bullseye format
What is Imminent Threat Warning (ITW)
Surface-to-air threat warning from a C2ISR platform to a friendly assest
When a friendly aircraft is within 5 NM of any active, awake, launching or firing threat
What is this?
HOSS 1, AGENT, EIGHT ACTIVE BULLSEYE 0-1-5/9
Imminent Threat Warning (ITW)
Explain Trespass
Called when an aircraft is within the MEZ of a surface-to-air missles MEZ that was previously unknown (e.g. tactical SAM)
What is this?
HOSS 1, TRESPASS SIX BULLSEYE 1-5-5/52
Trespass call
Explain Combat Advisory Broadcast (CAB)
Active surface-to-air threat emitters are passed on the tactical frequency using prebriefed labels or digital bullseye format
Not a threat warning
What is this?
BANDSAW, TWO ACTIVE BULLSEYE 0-3-5/8
Combat Advisory Broadcast
Contents of a Join Message?
Callsign/Mission Number/Type ETA Serviceability Operating Intentons/Limitations Planned Operating area & heigh/height block Latest SPINs changes Weapon load out Crew Compliment
Contents of a Handover message? 8
Estimated time of departure/off-station time Current Tasking Issues encountered/expected Other callsigns operating in area Comms Nets/Data Links Weather in area Departure Point and Flight Level Threats in Area
Explain Join and Handover Messages
Used to enable timely & seamless exchanges of information between oncoming and/or off-going units
What is an ELNOT?
ELint NOTation
Unique 5 character alphanumeric identifier for a specific emitter
Explain the structure of ELNOT
First character = Platform and originiating block
Middle three numbers - Just a sequence
Last character = Indicates family relationships
