#30 Elgamal Cryptography Algorithm - Asymmetric key cryptography |CNS|

[@saisasidhar8006]

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

[@dineshreddy.m6112]

Madam can you please make a video on elliptic curve cryptography

[@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😂

Mam last 3 assuming not understood 🥺

[@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

[@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

[@Adi-x4i]

Maam ur the best in teaching

[@renmarbalana1448]

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

[@TroubleFreevideos]

Glad to hear that

[@mohammadamanalimyzada1462]

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

[@subhadarshikar]

Tomorrow my exam in next 8 hr 🙂

[@satyamtiwari7102]

mam aj exam hai videos bhj do pls

[@itsZahid22]

thanks

[@collegematerial5348]

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

[@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 🙂

[@vikrams788]

Perfect explanation.

[@ManishSharma-hr1xc]

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

[@reshna225]

Last part is not clear

[@asmazaynab8927]

is there seal (software optimized encryption algorithm )in the playlists

[@gamerjones7491]

Do videos on Artificial Intelligence

[@sherinsuganthi6095]

Really superb 👌 and excellent presentation mam

[@ajeetbharati6948]

thank you mam provide this lecture

[@ashokg1833]

Akka plz principles entrepreneurship notes 4th year akka and data mini 2unit plzz

[@ansalrajjames2229]

Today afternoon is my exam😢

[@rohithravinuthala7540]

please upload elliptic curve cryptography mam

[@nuvoletta007]

i had to put 0.75 velocity to keep up but thank you :)

[@nerdgammer3073]

Brain is fast

[@rudomuchenje8537]

Good explanation but speed is too fast

[@user-um6dh5vr4u]

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

[@ramyagowthami6246]

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

[@surendrasriramula8748]

Thank you So much Madam

[@user-ip5kw6yv3f]

Thank you 👍

[@godofwar8262]

It is a copy video of easy engineering class 😂

[@neetjee8544]

Yes

[@user-ft1dn8mv8s]

how we are assuming everything here?

[@Shahab-ud-dinGhori-cm7em]

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

[@deepakd544]

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

[@shubhamjaiswal7645]

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

[@challaamanenderreddy1824]

kirak explanation maam

[@Prashant-ql4zh]

maam kl mera paper h , dua karo ki pass ho jaau

ecc algorithm pe bhi video banaye

[@irfansk2502]

Try to make a complete video without cutting in btw

Mam you are too good but your speed was too fast 😅

Thanks 🌹you mam

[@search_me_tilak]

Today is exam ok

[@sneham5516]

Mam..At 3:11 .. 8 mod 11=3 right? 🙄🤔

[@SanjivJaiswal-lx2uf]

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

[@creatorofimages7925]

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

[@nickatytepro8690]

are u buying these comments because the video is incomplete still no one is telling anything about it

[@muthyalaraghavendra1654]

Tomorrow

[@hawkeye8029]

kll Hi Hai...🥲🥲🙂🙂

[@midzy9639]

Its calculating, not caliculating...

[@ashwinpshaji4585]

U r so cringe

[@hindustanimanav]

so many assumptions , have to memorise it now
wtf

[@midzy9639]

Its calculate, not caliculate

[@syrabanushaik5634]

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

[@atiqueahmed4908]

kindly speak slow

[@kshitijsakpal1826]

why are you in a so much hurry while teaching ............

[@MadaraUchiha-wf3gk]

isse bura cryptography method nahi dekha mene aaj tak

[@dharanigadrawing]

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..... 🙂

[@ShristiKamble]

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

[@midzy9639]

Its calculation, no caliculation

[@varunsoni8991]

its south accent

[@nerdgammer3073]

Ok Shashi Tharoor

[@PirateHunter335]

poora copied video hai

[@MdNahid-hd4qo]

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
