Considering the sequence diagram, explain three improvements (these should NOT be fixes for mistakes found in a) ) that could be made to the current mechanism to improve security.

You may wish to consider:

Authentication factors used.

Transmission between the parties.

Attack susceptibility.

How credentials are stored

Then create your own sequence diagram with symbolic notation (as shown previously), for each process. Your diagram needs to both fix any outstanding notation issues (including those identified in a)), and incorporate the improvements suggested in b).

Training-4-U has asked you to analyse the following sequence diagram that they use to implement any authentiration f fnction within the romnan ] The followviny invauvi io alo noou inoro. - a= Account ID - p= User-provided plaintext password - w= Stored plaintext password - ca= Session code for Account ID - E()= Encryption function - D()= Decryption function - H()= Hash function - kr= Server's Asymmetric Private Key - ku= Server's Asymmetric Public Key
