Sir, i m a student of NIT Allahabad. You explains topics very clearly. I studied your graphics course too. Most faculties in my campus are not up to your mark . Keep posting such videos, It helps us a lot.

superb Sir, you have cleared out my all confusion, thanks Sir I love Indians Teacher. Love from Afghanistan

hello i am Desmond Oppong from Ghana- University of Education, Winneba-Kumasi Campus. I have enjoyed your lectures. And it has help me more to learn more about computer security. YOU ARE THE BEST

Sir I really like the way you teach a topic, the teaching speed and revision of the topic after detailed explanation has really helped understand the topic well. Thank you so much for making such videos :)

thanku sir your classes are extremly helpfull to my studies.. before i watched this i had planned to skip digital signature portion of cryptography.but now i understand about the concept. And these tutorials are really helping...thankuuuu sir

the best detailed and clear explanantions on entire youtube

NICE SUPER EXCELLENT MOTIVATED

Sir this digital signature lecture is very helpful thank you so much

Sir you have helped me a lot sir during my exams time. Your explonation is very goood and clear. Keep maintian that sir. You are one of the best teacher in my study career. I was scared about this subject and i found you on youtube. Now i learned lot of subject. Thank you very much sir.

Hi sir, your teaching is good sir keep uploading videos like this it is very helpful for students

thank u so much sir... .. easy to understand all the concepts in a simple way ...

Assalamulaikum sir grateful to you...😀.I didn't find it anywhere except here.😊.you explained in details.love this part of your lecture so much.keep It up sir.From bangladesh

Thank you sir, you explain the topics in a simple manner yet they are presice and helpful.

Why there are two algorithms RSA and DSA , what is difference between them ? How they are implemented physically ?. How global elements are distributed in DSA ?

Sir your all lectures are really helpful thanks and carry on

I like your videos .,.,.......,.very helpful from Zambia

you are very smart and good instructor

Very thanks. Great video.

Better than my college teacher...please keep up the good work !!

Thankyu sir ...u make evry complex thing so simple..

Superb Sir. Thank you so much.

Sir. Your lectures are very useful.thank you..

Great sir, well explained. Thank you

Sir u r vedios are very easy to understand .sir plz make vedios on Direct and arbitrated Digital signature and authentication protocols .thank you sir for making such useful vedios

Sir explanation is very precise and clear. Could you please take a value and show us how it will be calculated as per the formula you have mentioned.

Nice explanation sir , clearly explained DSA.

Thanks for sir. This helps in my exams .

Great sir

Awesome sir

Clear and Nice explanation , Thanks sir.

Thankyou so much, Sir... Your lecture was really so helpful and I understood the topic very well.😊

Thank you, sir, the video was very helpful

superb sir

Thank you very much sir ! helped a lot !

thank you sir

can you please make a video using the numbers as an example for this approach.So,that we can understand this much better

It's very difficult to remember all the formulas. Please, can you also provide some tricks to remember them so that they can be useful in exams.

Thank you so much sir... It's more useful for my class seminar

hello sir my compiller is not displaying nothing in output, while doing while loop, eventhough everything is correct, its displaying blank output, please help me.

Sir kindly prepare a video on ELLIPTIC CURVE CRYPTOGRAPHY plzzz. Lot helpful for me

nyc explination

sir, ur classes are very helpful ..but the only problem is the video is very lengthy

Thank you Sir

Thank u sir

good lectures sir

very nice

you are awesome man!

Can you tell if a Digital signature provides confidentiality or not, if so why? Thanks in advance.

Thank you sir.

Why people like you can't come to our universities and teach us😭😭😭 we are sooo helpless

excellent

Sir here s' and s will b same? as no function or anything is performed in s

Thank you very much

How receiver get sender private key please clear my doubt because I am noob

Public and private key confusing how it will work 😭😭

Hello sir, it a very clear presentation Just to know whether this DSA process is fixed in all the cases with the same steps and formulas? Or any variance form customer to customer

sir, randomly I searched for something but I saw ur DES algorithm then I got interested in knowing the network security concepts, but how do I apply these concepts for the Hardware security work I finding? Can u give any ideas how these concepts can be applied for intellectual property(IP) of FPGA can be identified and authenticated

nice explanation

Sandeep sir... kindly do a video on ELLIPTIC CURVE CRYPTOGRAPHY plzzz

In RSA algortm not explain where the PUa /public key come from? Isit generate at fist time sending plaintext?

Sir:: Share a video of "An optimum secure authenticated key exchange scheme for Vehicular Cloud Computing using Schnorr Signcryption with Hyperelliptic curve cryptography " convey the concept of VANETs, Cloud and it's security..please

both sender and receiver should exchange this Public key component P,q,g,h and k first or ?

In RSA digital signature approach we encrypt only the hash functions right? How does this ensure That only A is sending?? Confused...

hello sir, so in the first example. Do we use RSA encryption instead of Private key or we use both?

why sha 1 and not sha 3 ?

I have a doubt... if A wants to send a message to B. And A encrypt the message with his own public key, then its only possible to decrypt with A's private key. right..? so how B will read that message....??

thanks

THANK YOU SO MUCH!

In which signature algorithm uses only one fourth of the keysize for digital signature generation

Sir plz tell difference between r and r' ...?

Sir: please do a video about schnorr algorithm as soon as possible

Thank you very much :)

Sir What is the difference between rsa and dsa? When do we have to make use which approach ,how do we come to know?

Sir nice video but why don't you explain dss alogorith with example so that it will be more clear

Hi Sir, I appreciate for your hard work in making such an awesome content for us. my doubt is.. at 7:00 in (DS using RSA algorithm) plaintext -->hash--> hash is encrypted using private key of senders --> then the encrypted hash message is appended with the plain text message and sent to the sender.. but here comes my question!! are we going to send that plain text msg along with hash ? that's not secure right?

thanks Anna!

Sir could you plz tell me ....Which cipher is the permutation cipher?.....is it Permutation cipher are discrete mathematics in Cryptography

Considering that i am requesting to google.com but on the way it is intercepted, destroyed and responsed by a man in the middle. Is it possible if a man in the middle intercepts and destroyes the senders request along with certificate and sends his message with his certificate issued by a trusted CA? How will the receiver know that he is talking to the person(google.com) he intends to, can it invalidate the certificate of the middle man?

how to find the inverse?

Thank you so much sir. : )

Example qtn ...pls..

how can i find the Alert in selenium video thanks

Hai sir I am research scholar any idea research topic in network security tell ur valuable suggestion

why only r is taken when comparing in dss approach

30:31 Whiteboard full view. Thank me later!

sir plz explain math behind dsa

Sir how to find k inverse

public key encrypts private key decrypts. why are telling opposite? i am not trying to prove u wrong. just asking

How Global variables are shared to B ?

Sir why we are doing encryption for hash code already it is a fixed code length

Sir if we encrypt with private key 🔐 then in a network any one can decrypt it with public key nah sir ?

Please explain fermat's theorem Feige fiat shamir Ing schnorr shamir Pls sir, exam on Wednesday

Please make vedio on symmetric key distribution using asymetric encryption and symmetric key distribution using symmetric encryption

Tq sir

sir can u pls take a question on DSA

Plz explain through one example

Sir kindly release cmac, whirlpool, blow fish, rc4,ecc

SEJH JI KI JAI HO,PASS KARWA DIE🙏🙏🙏

please explain elgamal digital signature algorithm with example

Any one have the full playlist of this videos
