This paper presents a reconfigurable system that can encrypt digital data. The system provides the option of choosing one of familiar encryption methods DES, 3 DES and AES to the user. All these methods are symmetric type block cipher cryptography. DES takes 64 bit key to encrypt each 64 bits block of the entire message. AES on the contrary takes 128 bit(More)
A simulation based project is designed which can be practically implemented in a workspace (in this case, a barber shop). The design algorithm provides the user different time varying features such as number of people arrival, number of people being served, number of people waiting at the queue etc depending upon input criteria and system capability.
