NETWORK SECURITY - TYPES OF AUTHENTICATION (Message Encryption, MAC, Hash Functions)

Three types of Authentications
1. Message Encryption
2. Message Authentication Code
3. Hash Functions.

I had so many "Oooohhhh!!" moments during this. Thank you so much!

[@jirilzala7573]

Thank you so much sir. I was trying to understand this for last 3-4 hours but everywhere it was over complicated but thanks to you now i'm clear. Thank you again teacher because you are providing and sharing your precious knowledge with us. I'm so inspired by you after seeing you teaching with this passion. Best wishes sir.

Hi Very nice to see your comment and thanks for your support towards our channel.

[@mayankbhagat4154]

Sir your lectures were really very helpful. You are an outstanding teacher. I would like to suggest that after explaining each of the authentication methods or cipher algorithms you should have explained their advantages and disadvantages. That would have given us more insight. Thanks

[@a.yashwanth]

36:00 there is no need to encrypt hash code separately as the entire plain text and hash are encrypted using the key only known to those 2 people. You encrypt the hash code only when the message is sent in plain text format because anyone can modify the PT and recompute the hash code and the receiver doesn't know if the hash is not encrypted.

[@ashidevkc9003]

great one

[@essarshed5197]

Sir. Your classes are excellent. Good to polish fundamentals. Could u give me examples (names) of some algorithm for 2nd and 3rd methods( for Message Authentication Codes and Hash Codes).

[@sagnikchakraborty165]

sir in case of hash function can't we encrypt the hash code using secret key i mean symetric key cryptography technique?

[@sundeepsaradhi]

hi chakraborty of course you can encrypt the hash code with secret key and the same should reflected on receivers side.

[@Michelle-rb6nl]

thank you!🤯

[@gopinathpanda5889]

sir I have a doubt in hash code. in case-2 of hash code the hash code was decrypted by public key of A.Which is available for all users and anyone can decrypt it.there is no use of private key.How this can be achieved.

[@a.yashwanth]

26:00 if we want only authentication, then what's the point of encrypting the plain text. Only encrypting the MAC is enough. If someone wants to change the PT then he cannot recalculate the MAC and modify it as he won't have the key to encrypt it. edit: oh, that's what hash functions do.

How does the receiver get to know the MAC code that was applied so that it can it can be compared with the senders MAC?

Thanks

hi hasan thanks for watching my sessions and interest towards our channel.

[@chsaidattapavanbalaji7996]

Thankyou Sir

[@sudhanshujha5408]

Sir can you please tell how come the authentication is achieved in 3rd case of message encryption because there reciever is not recognised by the sender and as you say for authentication both should recognise each other so it fails as per that concept🙄

[@sharonrosy9519]

Tq sir

[@arian7472]

just can you correct me if iam worng hash function is md5 , sha , hmac the first one without shared secret key is md5 or sha the second one with using shared key is hmac

hello sir,you are saying that hash is independent of key,but in second case your are using secret key for the encryption of the whole message,why?

18:11 MAC

[@mubashareenahmad2404]

What are the authentication functions (c) and hash functions (h) we are applying for the plaintext ?

[@sundeepsaradhi]

hi here the Receiver should know whether the received message is sent from valid and authorized user and this process is called authentication and also the message should not be altered during the transmission and this process is called Integrity. In order to achieve authentication and integrity we will use authentication and hash functions. Hope your doubt has been clarified.

[@Sourav9835]

How the secret key will be generated and shared between sender and receiver
