VLAN

VLAN stands for Virtual Local Area Network, and it is created from one or more local area networks. A Virtual Local Area Network (VLAN) is a customized network made up of one or more LANs. It allows a set of devices from different networks to be converted into a single logical network. As a result, a virtual LAN that is managed similarly to a physical LAN emerges.

In modern encryption, plaintext is encoded in binary form. Each bit in a bit stream is encrypted into its matching ciphertext, while bits in a block stream are grouped together to create groups of bits prior to encryption.
Instead of encryption, the middle component of triple DES is decryption.
The hacker group Desdeia tries to break our old weak cipher which we used for the communication with the Duchess of Ligovia. It's generally known that an actual breaking of the cipher needs the reviewing a huge amount of variants which probably lasts a couple of months. Additionally we know that the reviewing of different variants needs always the same server resource. Using our intelligence sources we tried to get some information about the actual progress of breaking, but we got only some fragments: • The hacker group Desdeia uses for breaking their powerful four-core server which resources are fully dedicated to breaking process. . The actual breaking process began exactly at noon, but we don't know, on which day. . By the noon of 2nd of April, already 648,467,673 variants were successfully reviewed. Exactly at this noon, when the breaking process was already lasted for 19 days, it was attempted to double the server speed. The doubling itself was failed, but instead of it there was…

Describe the process between sender and receiver for asymmetric encryption
In modern encryption, plaintext is encoded in binary form. Each bit in a bit stream is encrypted into its matching ciphertext, while bits in a block stream are grouped together to create groups of bits prior to encryption.
Encrypting with TDEA and a single key is pointless, because it is equivalent to encrypting with the original "single" DES, which is no longer considered strong enough to resist feasible attacks. In your own words (do not quote in any way from any source), briefly explain why decrypting with TDEA and a single key was a useful operation when TDEA was developed.
