144-Bit Encryption/Decryption Technique

In this paper, the authors introduce a new 144-bit cryptographic algorithm. This is done using a 16-segment electronic display and arranging the bits in a rectangular matrix and then converting it into nearest square matrix with the addition of dummy bits and rearranging the individual bits by a newly proposed mathematical approach. The bit code is generated for each corresponding alphabets/numerals/special symbols in the 'PLAIN TEXT' depending on the LED's which glow, when they are represented using the 16- Segment displays.
