A Look At Public Key Encryption



Encryption is the process of disguising information by transforming
plain text into gibberish, or ciphertext, which cannot be understood by an
unauthorized person. Decryption is the process of transforming ciphertext
back into plaintext that can be read by anyone. Example of encryption can
be found in history, for example in the era of the Cold War, the Solviet
Union and the United States would send electronic messages to one military
point to another, encrypted. If the enemy intercepted the message, they
would have to crack this message to get the information. Typically when
governments used encryption they used a very complex method of encrypting
messages. Encryption does not have to be ...

key can easily switch the H back to a D, the V
back to an R, and figure out where to meet. Theses two examples are on
opposite sides of the spectrum, but both have their similarities and their
differences.
The major difference complexity, the government pays mathematicians to
research complex algorithms by which to encode the messages, like the
system used by Captain Video but these algorithms are complex enough that
if you tried to crack them it would take you decades with even the most
powerful computer today. This complex mathematical code is what makes the
text secure to anyone who tries to crack it. Some similarities we can find
in these two examples are their use of the key, the unlocking instructions,
to decode the message. They only used one key to encrypt and decrypt the
messages. This creates problems, security problems. The single key must
itself be kept very secret, while somehow still being transmitted to the
person receiving encoded messages. Even if the key is ...
