1) supposing the keystream is a stream that is of random bits in Z26, we can describe a stream cipher based on the Latin Alphabet that is as follows (where A ↔ 0, B ↔ 1, C ↔ 2 etc):

$y_{i} =x_{i} +k_{i}$ mod26

$x_{i} =y_{i} -k_{i}$ mod26

$x_{i} =y_{i} -k_{i}$ = ” B ” − ” R ” = 1 − 17 = − 16 ≡ 10 mod 26 = ” K ” etc ·

MaRussiya [10]

<u>Hi dear user! </u>

<u>Hope my answer helps you and solve your queries. </u>

First of all,

ISP which is an acronym of Internet Service Provider, keeps the track of all the activities their users perform through their network.

For eg :-

You have a connection of Airtel, whatever you will access through your Airtel network will always be tracked by your ISP which is Airtel. If you delete your search/download history from your phone/laptop, still it can be seen by Airtel, you cannot delete from there end. Even if you access anything in incognito mode, then your browser does not stores your data but your ISP still can see what all you accessed in incognito mode.

Now coming to your next question,

If you delete your data from your phone or laptop, it is still somewhere saved in the hard drive of that device. The file is deleted from the device but it's hard drive still have that file, and anyone can access to that data by using a certain software but for that, the person will also need your hard drive. There are certain softwares like Disk Drill which is used to recover the hard drive's data.

Hope your queries are resolved !
