The symmetric key must be shared only by two parties, i.e. this is because HMAC uses the symmetric key to generate MAC.

Somehow the above problem, the exchange of symmetric key is solved we cannot use the Hash-based Message Authentication Code in case of more than one receiver.

The problem that arises here is how the sender and receiver will exchange the key?. The symmetric key means the same key used by the sender and the receiver.

Let us discuss some problems that we may face in the Hash-based Message Authentication Code.Īs we have discussed earlier, the Hash-based Message Authentication Code uses a symmetric key.

Disadvantages of HMACīelow are some of the disadvantages given. the generated Message digest of this step is the final MAC. In this step, we will apply the selected message-digest algorithm to the output of step 6. In this step, we take the message digest, which is calculated in step 4 and append it at the end of the S2, which is derived in the previous step, i.e. Note: pad= It is a string 01011010 repeated b/8 times.
