[@dineshreddy.m6112]

Madam can you please make a video on elliptic curve cryptography

[@saisasidhar8006]

thank you for making such helpful videos for our exams
your videos helped me clear my exam with ease

[@coa51pakshalshah22]

Selecting e1 has a criteria , it should be a primitive root of selected prime number

[@thengakola6217]

its 7.40am now, can you make a video before 9.30am exam today?

[@sannihithreddy7207]

😂😂😂😂

[@NaveenReddy-zk7of]

Yes i will

[@HarshKumar-hn8ss]

haan bhai tere lie baithi hui h wo 😂😂😂

[@akshay_s_gupta]

At 7.40 u must be more focused on watching the video and learning rather than commenting😂

[@erenyayger3840]

🙊

[@renmarbalana1448]

Very nice, explained what my prof couldn't in a 3 hour lecture

[@TroubleFreevideos]

Glad to hear that

Mam last 3 assuming not understood 🥺

[@mohammadamanalimyzada1462]

7:00 For finding mod inverse we can use little format thm
Btw thanks fir the videos

[@LegolasSmith]

for anyone interested you can use extended euclid theorem for finding modular inverse

[@nitac2237]

isnt 125^-1 mod 11 is 1?

[@learnonline2917]

no its 3

[@chaitanyasharma6920]

i didnt get the last mod part
please explain another way

[@Adi-x4i]

Maam ur the best in teaching

[@vikrams788]

Perfect explanation.

[@niharikaakula3618]

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

[@collegematerial5348]

Decryption go with public key? 5:09
Please clear my doubt

[@coolsai]

Just going in exam hall 😂

[@rudrakshsharma3847]

Best of luck brother

[@coolsai]

@@rudrakshsharma3847 thanks

[@ShubhamKumar-l2u2x]

how we are assuming everything here?

[@shubhamjaiswal7645]

very nice explaination...vo sab to thik hai but last par cut kyu keya

[@sherinsuganthi6095]

Really superb 👌 and excellent presentation mam

[@rohithravinuthala7540]

please upload elliptic curve cryptography mam

[@dhaniharshini2980]

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 🙂

[@subhadarshikar]

Tomorrow my exam in next 8 hr 🙂

[@MAHENDRATAVATE]

Thank you 👍

[@sneham5516]

Mam..At 3:11 .. 8 mod 11=3 right? 🙄🤔

[@SanjivJaiswal-lx2uf]

No, it's 8. Btw, 14 mod 11 is 3.

[@satyamtiwari7102]

mam aj exam hai videos bhj do pls

[@mooon1631]

how am i supposed to memorize all of that... :(

thanks

[@ramyagowthami6246]

hi mam kindly post how to solve large no of mod values ...ex 123^45678

[@deepakd544]

Madam where do we used public key that is what we have generated in the first step for encryption..

[@Musicalmelody_1]

Pls show calculating part in calci

[@ManishSharma-hr1xc]

mam can y explain one more example please. ineed little more clarity.

[@Shahab-ud-dinGhori-cm7em]

what you have done at last......!!!!!? i can't understand.

Assuming the exponent to be 3 is a not a clean way to do this!

[@irfansk2502]

Try to make a complete video without cutting in btw

[@ashwinpshaji4585]

U r so cringe

[@Lusty-p1s]

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

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

[@TroubleFreevideos]

Sorry about that, i will definitely try to improve it

[@th_jackdragon007]

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..... 🙂

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
