Cryptography/Caesar Cipher Encryption/ Matlab Implementation with in 3 Min

Networks security is one of the most important aspects nowadays especially with a massive number of multimedia devices world wide. Hence the cryptography subject have a lot of attention and gained a huge interest among the researchers.
This video show a simple way for writing a Matlab script to implement the encryption process of the Caesar cipher. Caesar cipher is simple cryptography technique invented before many years ago, it is based on letter shifting principle according to predefined shifting key.
