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

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.

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.

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

@sundeepsaradhi 4 жыл бұрын

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.

Hi In order to generate hash code we need not use of key on plain text but for acheiving the confidentiality we will encrypt the plain text along with hash code. Hope your doubt has been clarified.

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🙄
