higher management sitting in Australia & Dubai campuses. Any data outflow and hacking can cause downfall of the University‚ so a secure communication is needed among all campuses. Let’s say that the messaging is done by implementing the public key cryptography under the digital signature technology. There are number of processes done on sender and receiver side to secure the messages and keep them safe from hackers. Now answer the below questions from the above mentioned scenario;

1. Frequency Division Multiplexing Frequency Division Multiplexing is a technique that can be applied when bandwidth of the link is greater than combined bandwidth of signals to be transmitted. Frequency Division Multiplexing technique is the process of translating the frequency of individual channel into per-assigned frequency slots within the bandwidth of the transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier

III. DIFFIE-HELLMAN KEY EXCHANGE ALGORITHM Hilter kilter Encryption of information requires exchange of cryptographic private key. The most difficult part in this sort of encryption is the exchange of the encryption key from sender to beneficiary without anybody capturing this key in the middle. This exchange or rather era on same cryptographic keys at both sides cryptically was made conceivable by the Diffie-Hellman calculation. The Diffie-Hellman calculation was produced by Whitfield Diffie and
