NETWORK SECURITY - PUBLIC KEY DISTRIBUTION

[@glensaldanha3485]

Love the passion of this gentleman...

[@pavitrasinghtomar1979]

what a straight Explaination it was ......!!! Understood the CONCEPTS IN SHOT....BRAVO!!!

[@amkeertana9713]

Thanks a lot sir,all the videos were crystal clear..helped me a lot for my exams.

[@EllyHejazi]

It is really good explanation . Thanks for wonderful tutorial. 👌👌👌

[@syedshakeel2857]

Sir, This is such easy explanation to follow with example and details. Thank you for such videos.

[@ssn5223]

i love how he uses the duster after writing anything

[@DeveloperJunaid]

I Love Your Teaching Style !!

[@Baltejgoud]

Thanks!

[@sundeepsaradhi]

Thank You My Friend for your love and support towards our channel. Share our sessions with your friends. Thank You once again.

[@parveshtaneja2005]

Sir, I am going through your videos and it is really helpful to understand the concept and algorithm. Thank you very much.

[@imabeapirate]

Thank you for this upload and sharing the knowledge!! Learned a lot!

[@hiteshgorantla1566]

In public-key authority 19:42 point 3,6,7 It should be PU instead of KU as it's the public key of a and b not of PKA.

[@lks5343]

Nice explanation , my all doubts get cleared . Thank you sir .

[@rajeshkumarrout0141]

Nice Explanation 👍👍

[@sherymalik5835]

Where were you man? Awesome explanation..Cleared all my concepts. Thankyou so much .

[@ptit9x]

Thank you for this lession, it very helpful with me

[@gaming_boga]

Sir you are great thanks a lot for your teaching

[@siripanchadi6288]

Soooper.. ! U explained it very clearly ..thnkew

[@niharikareddy_ars]

Very good explanation sir. But if u explain it in less time u will gain more viewers because many of us will see the concepts during exams and we won't get that much time to see each concept.

[@a.yashwanth]

for the public key distribution, you told that certificates are encrypted by private key of authority so that anyone can verify if the certificate is valid by decrypting with CA public key. But how do you distribute the public key of CA in the first place?

[@swagplayzyt]

Sir , complete the syllabus of network security as soon as possible . My exams are coming , and l'm waiting to see your video. Thanku u sir

[@sundeepsaradhi]

hi rishabh thanks for your interest towards our channel. Soon i will upload all the concepts.

[@JMacSD]

Thanks for this wonderful tutorial on key distribution! But while it shows how authentication is performed in these key exchanges, that part seems exploitable, for instance: In 3) Public Key Authority: A sends his ID(A) to B [encrypted with KU(B)], why is B sure this message came from A? Anybody who knows ID(A) could have sent it, right? For example, say now B wants to talk to F while fooling F to think he's talking to A, so B sends ID(A) where he's supposed to send his his own ID(B): how can F know this is a lie? In 4) Certificate Authority: Now B wants to fool F so B sends C(A) instead of C(B), F can look at the time stamp in the cert and hopefully see it's too old, and B's lie fails.

[@rg_arts_81]

Nice explained sir

[@rinzinnorbu3518]

wow really nice explanation thank you sir

[@sundeepsaradhi]

Hi Rinzin Thanks for your support towards our channel share our channel with your friends and keep following our channel

[@sajalrastogi3904]

private key authority will be different for different users right ?..... so we should right KRauthA or KRauthB right?

[@yusrameraj91]

Best lectures..Thank u sir

[@pranavkakade7440]

Thank you sm . Helped a lot

[@Soni-Santosh]

Best Video ever seen

[@Vishva-h6n]

Thank you very much sir. i easily understood your class

[@niharikaniharika9536]

sir in last 30.24 cA is encrypted by private key of certificate authority,which is present only at certificate authority,how user A,B C can decrypt message

[@krishnaprasath4341]

Sir, In public key distribution Certification Authority send Certificate to UserA, user B. It will Encrypted by certificate authority, my doubt is who is decrypted user A or user B

[@pranavbhokare1866]

How that encrypted message of authority is decrypted at end of user A and User B , If that msg are encrypted using private key of authority which is not shared to any user ?? And if in case that the msg are decrypted using public key ,then ther will be vulnerabilities in system as everyone can get each other's public key anyone user can decrypt that msg.??? PLZ reply ASAP

[@navneetnigam114]

how can we decrypt the certificate of any user? it is encrypt with private key of certificate authority.

[@aseenaa3931]

Sir can we compare public key distribution system with public key cryptosystem

[@arian7472]

public key send without any encryption to CA yes ?

[@jewel.barman]

Can you also Make a video on SSH(Secure Shell) describing all it's key exchange?

[@RaviKant-kp9fs]

very good video sir

[@jajamnagasreeja8835]

thank you so much sir

[@NareshKumar-bl3sy]

very Nice !!! as Expected.......

[@sundeepsaradhi]

hi naresh thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

[@sushailya]

Hello Sundeep garu. In key distribution through Certificate Authority, how is the Public key of the CA distributed among the users? Can you please explain?

[@sundeepsaradhi]

hi sushailya thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel. soon i will to upload.

[@subhendubera7348]

in asymmetric key encryption techniques support n user want to communicate, how many different public key and private key will be used for this scenario? sir ans. pls

[@sundeepsaradhi]

in Asymmetric key encryption both the sender and receiver will be having public and private keys. SENDER A = { PUa , PRa } RECEIVER B={ PUb , PRb } hope your doubt has been clarified.

[@freddiegellar4839]

Sir, if public key of authority is available to everyone and the public key authority uses it's private key to encrypt the public key of the intended user, then anyone could decrypt the message and get the public key of the user. Then, what's the use of even encrypting it?

[@remyaunnikrishnan2037]

only the registered users know the public key of the authority

[@b2-mani]

@@remyaunnikrishnan2037 cool

[@satishkumar-vs2xh]

Here encryption means which encryption algarithm is used sir?

[@gauravthapliyal7523]

Hi Sandeep Great videos. How ever, if you could please explain using some practical scenarios. Like, in CA case, you say that user A will send its public key to CA and inturn CA will give a CERT to A. Now my question is what if an evil guy gets the public key of say Amazon and ask CA to generate a cert for it. Obviously, CA wont generate a Amazon cert for that hacker. But what exactly happens there and a lot of questions like that.

[@a.yashwanth]

You need to authenticate with the CA before doing this process. The main point of a CA is to verify if you are the one who you claim to be. For example, if you want a certificate for your website then you need to prove that the domain for which you want the CA belongs to you. Unless you do that you will not get the certificate for https.

[@pavant8761]

Sir. .. actually why a public key should be distributed? Only text can be passed but why the purpose of KEY DISTRIBUTION? Kindly clarify.

[@sundeepsaradhi]

Hi In order to do the process of encryption and decryption we need a pair of keys. Without the pair of keys these process can't be done.

[@devarakondavenkatasuryanag737]

Hi Sarahi, your sessions on Network Security topic are very detailed and useful. o you have any sessions on the basic mathematics require like Galios fields abstract algebra

[@asemal-abdali9795]

great job man

[@vaskaran1]

Do u have chinese remainder theorem?

[@sundeepsaradhi]

hi Vasantha raj garu sorry i dont have the video of Chinese remainder theorem but having an idea to do that video and soon i will try to do that.

[@kebedenibretu9711]

Thank you Sir. for your nice tutorial. but i have 1 question, at the 4th method of public key distribution (certificate authority), how user A and User B know the private key of certificate authority? Because when they start communication, each user encrypt their 'identity' and 'Timestamp' using Private key of Certificate authority.

[@haripriya5836]
