thank you for making such helpful videos for our exams
your videos helped me clear my exam with ease
Madam can you please make a video on elliptic curve cryptography
its 7.40am now, can you make a video before 9.30am exam today?
😂😂😂😂
Yes i will
haan bhai tere lie baithi hui h wo 😂😂😂
At 7.40 u must be more focused on watching the video and learning rather than commenting😂
Mam last 3 assuming not understood 🥺
for anyone interested you can use extended euclid theorem for finding modular inverse
isnt 125^-1 mod 11 is 1?
no its 3
@@nitac2237
i didnt get the last mod part
please explain another way
Sis please make a video on elliptic curve cryptography post that as soon as possible I can understand only ur videos which are simple and fast
Maam ur the best in teaching
Very nice, explained what my prof couldn't in a 3 hour lecture
Glad to hear that
7:00 For finding mod inverse we can use little format thm
Btw thanks fir the videos
Tomorrow my exam in next 8 hr 🙂
mam aj exam hai videos bhj do pls
thanks
Decryption go with public key? 5:09
Please clear my doubt
The video is gud, it has the example well explained, but the concept is not properly conveyed, it would be more helpful if the concept and theory is also added to all the videos Thank you 🙂
Perfect explanation.
mam can y explain one more example please. ineed little more clarity.
Last part is not clear
is there seal (software optimized encryption algorithm )in the playlists
Do videos on Artificial Intelligence
Really superb 👌 and excellent presentation mam
thank you mam provide this lecture
Akka plz principles entrepreneurship notes 4th year akka and data mini 2unit plzz
Today afternoon is my exam😢
please upload elliptic curve cryptography mam
i had to put 0.75 velocity to keep up but thank you :)
Brain is fast
Good explanation but speed is too fast
at last she made wrong
you can correct it through this comment
A. EI gamal key generation:
Select a large prime number ‘p’
Select encryption key ‘e′1
to be primitive root of mod p
Select decryption key ‘d’ such that 1≤d≤p−2
Select encryption key ‘e′2
such that
e2=ed1 mod p
Form the set i,e public key (e1,e2,p)
to be announced publicly
Private Key 'd' to be kept secret.
B. EI gamal key encryption:
Select a random number ‘r’
Compute the first part of ciphertext ‘c′1,c1=er1modp
Compute the second part of ciphertext ‘c′2,c2=(er2∗PT)modp
C. EI gamal key decryption:
Calculate the PT
PT=(c2∗(cp−1−d1))modp
Example 1:
let Plaintext M = 7
e1
= 2
d = 3
Random no 'r' = 4
1. Key generation:
p=11e1=2d=3
e2=ed1 mod p=23mod11=8 mod 11=8
2. Encryption:
c1c2Random no r=4=er1 mod p=24 mod 11=16 mod 11=5=Pt∗er2 mod p=7∗84 mod 11=28672 mod11=6
3. Decryption:
PT=(c2∗(cp−1−d1)) mod p=(7∗511−1−3) mod 11=18 mod 11=7
Example 2:
let Plaintext M = 6
e1=5d=2Randomno′r′=4
1. Key generation:
P=7,e1=5 and d=2
e2=ed1 mod p=52 mod 7=25 mod 7=4
2. Encryption:
c1c2Random no r =4=er1 mod p=54mod7=625mod7=2=Pt∗er2 mod p=6∗44mod7=1536mod7=3
3. Decryption:
PT=(c2∗(cp−1−d1)) mod p=(3∗27−1−2) mod 7=48 mod 7=6
Using chatgpt 😏 showing himself has an intelligent
hi mam kindly post how to solve large no of mod values ...ex 123^45678
Thank you So much Madam
Thank you 👍
It is a copy video of easy engineering class 😂
Yes
how we are assuming everything here?
what you have done at last......!!!!!? i can't understand.
Madam where do we used public key that is what we have generated in the first step for encryption..
very nice explaination...vo sab to thik hai but last par cut kyu keya
kirak explanation maam
maam kl mera paper h , dua karo ki pass ho jaau
My exam on 22 Jan vtu syllabus
Mam there is no problem solving and problem solving methods topics
Thank you..
kaa .. enna ka kadasila ans ehh solama thank you solringe!
aama bro enakum last la puriyala odaney thanks solli mudichutaanga tomorrow exam vera 😅
Hii mam can you give the notes pdf
ecc algorithm pe bhi video banaye
Try to make a complete video without cutting in btw
My exam on 22 Jan
125^-1 mod 11 is 1 not 3
Mam,share a total PDFs file mam..!!
Thanks for medam
how am i supposed to memorize all of that... :(
maam aapne ed=nd me nhi btaya kese krte h ;
Thanks akka

Good
Thanks akkka
Thanku yar
Mam you are too good but your speed was too fast 😅
At 6:44 it is answer......
hi mam im having exam on monday i.e(19/12/23) pls tell me how to prepare
Thanks 🌹you mam
Today is exam ok
Mam..At 3:11 .. 8 mod 11=3 right? 🙄🤔
No, it's 8. Btw, 14 mod 11 is 3.
Assuming the exponent to be 3 is a not a clean way to do this!

Hi you are very cute, next time if you teach please switch on your face-cam.
Nice video BTW
are u buying these comments because the video is incomplete still no one is telling anything about it
Tomorrow
kll Hi Hai...🥲🥲🙂🙂
Its calculating, not caliculating...
U r so cringe
😒
Exam Schedule - 17 minute mei exam hai
today
so many assumptions , have to memorise it now
wtf
Its calculate, not caliculate
1 ghante mein hai paper

Whole explanation was too excellent but the sound which u make while swallowing ur spit is too annoying and that sound is making me to distract please check it once keep ur mic some what away from the mouth
kindly speak slow
why are you in a so much hurry while teaching ............
isse bura cryptography method nahi dekha mene aaj tak
This not helpful to me ..calculating steps you already written so you explore but we couldn't now that...your fast teaching also
...it's like poor video to me
Sorry about that, i will definitely try to improve it
You can't even understand this simple problem that much dumb you are 🤡 and if it is fast, UA-cam has an option for changing the speed of the vedio 🤡 I watched this vedio in 1.5x speed it was very simple..... 🙂
Worst online teacher ever, she just can't explain anything clearly. She's just running to complete the topic asap, ending me toh kya ki khudko hi pata
Its calculation, no caliculation
its south accent
Ok Shashi Tharoor
poora copied video hai
Pata h kya jab teacher koy female rahe to english bolna jarrori h kya jbki male teaher bhi english jante h fir bhi itna english use nhi karte hai kyonki unko pata h ki jo begineers rehte h unko problem hoti hai so apse requst hai ki pllss make video in hindi
