J1 Jamming device

Description
Features
  • Brute force attack
  • Dictionary attack
  • Whitelist function
  • Attack list function
  • Attack sends nan and on-off signals



Installation method
①Please move it by cut and paste
②Connect the power node



Basic operation
①Turn on the power.
②Find the frequency used by the other party in search mode (The frequency used by the other party is automatically registered in the attack list)
③ Attack the frequency registered in the attack list in attack mode.



About the whitelist
Whitelisted frequencies will not attack even if they are on the attack list
Please register the frequency you are using. (10000 or more complex frequencies do not need to be registered)

How to operate the whitelist
First, enter the frequency you want to register or delete on the keypad
If you want to whitelist that frequency, press "Add to whitelist"
If you want to remove that frequency from the whitelist, press "Remove from whitelist"



About the attack list
When in attack mode, it jams the frequencies registered in the attack list.

How to operate the attack list
First, enter the frequency you want to register or delete on the keypad
If you want to add that frequency to the attack list, press "Add to attack list"
If you want to remove that frequency from the attack list, press "Remove from attack list"
If you want to reset the attack list, press "Reset attack list"



About the screen
The top line is the current mode, the second line is the displayed list.
You can use the left and right buttons to switch the displayed list, etc.

A brute force attack is an attack that "brute forces" to check each frequency between -9999 and 9999.
A dictionary attack is an attack that checks only frequencies that are likely to be entered, such as "12345", "1111", or "31415".
Therefore, it cannot check complex frequencies with an absolute value of 10,000 or more (such as 67824, -54239, 3854972 or -974854315.
I gave them names like this, likening the "frequencies used" to "passwords".

ブルートフォース攻撃は、-9999～9999の周波数を１つ１つ、「力任せに」調べていく攻撃です。
辞書攻撃は、「12345」や「1111」、「31415」などのような、入力していそうな周波数のみを決め打ちで調べていく攻撃です。
なので、絶対値が10000以上の複雑な周波数はチェックできていません（3854972や974854315など）。
「使用されている周波数」を「パスワード」に見立ててこんな感じの名前をつけました。

How does the dictionary and brute force attacks work, and what are each?
猫好き  [author] 1 Feb @ 10:12pm 
合計で、20137個の周波数を傍受しています。
３本の傍受アンテナは毎秒180個の周波数を傍受します(1秒あたり60個ではなかったです。間違えました)。
ブルートフォース攻撃として、-9999～9999の周波数をを毎秒120個傍受します。
辞書攻撃として、138個の登録された周波数を毎秒60個傍受します。

In total, 20,137 frequencies are intercepted.
The three intercepting antennas intercept 180 frequencies per second (not 60 per second, I was wrong).
As a brute force attack, 120 frequencies between -9999 and 9999 are intercepted per second.
As a dictionary attack, 60 of the 138 registered frequencies are intercepted per second.

How many frequency does it scan in total?
猫好き  [author] 1 Feb @ 9:46am 
1秒あたり60個の周波数をスキャンできます。

It can scan 60 frequencies per second.

how quickly does it scan frequency

if value ~= value then
value = 0
end

このプログラムなら、妨害電波を受信しても攻撃を防げます。
J1は-nanを相手に送りつけます。このプログラムなら、nanと-nanに対応できます。
また、LUAには nan ~= nan や -nan ~= -nan が true になる仕様があります。
WT E100 28 Jan @ 12:05am 
if tostring(value)=="nan" then value=0 end
これで防げますか？

It is not possible to jam radar directly. Also, there is a possibility that the enemy's LUA will cause a bug if no countermeasures are taken, but if there is a countermeasure in LUA, I don't think there will be any bugs.

The mechanism is to check whether various frequencies are being used and send "jamming information" to the frequencies used by the enemy.
For "jamming information", nan is used for the numerical channel, and true and false are used alternately for the Bool channel.
