MATLAB code of AES Encryption and Decryption of Text

Nowadays Fast evaluation of digital data exchange is occurring. Due to that security of information is much important in data storage and transmission process. Security of internet banking account passwords, email accounts password etc. requires text protection in digital media. The National Institute of Standards and Technology (NIST) have initiated a process to develop Federal Information Processing Standard (FIPS) which should be most flexible, secure and fast which can replace Data Encryption standard. This new standard is recognized by name Advanced Encryption Standard (AES). Features of data are depending on its types. Because of which same encryption techniques cannot be used for all types of data. However, with few variations in method AES can be used to protect text.  

The matlab implementation of the above project is shown in the following YouTube Video. Just have a look.  


1. Symmetric key / Private key 
In this, the encryption and decryption keys are the same. Both the sender and the receiver must have the same key before they can achieve secure communication. 
2.Asymmetric key/ Public key 
In this method, the encryption key is published for anyone to use and encrypt messages but only the receiving party has access to the decryption key that enables messages to be read.
