Lightweight Hybrid Algorithm
Due to advances in IT infrastructure and its benefit people are adopting to ecommerce and digital communication
for their business growth and they prefer most of their business activity on computer and digital communication media. Due
to huge dependency on computer and electronic media chances of security risk increases on electronic data that is transferred
though insecure communication media from one place to another. Because electronic data can be intercepted when it is
transmitted through electronic media by some intruder. To provide security and accuracy to private data & information
various security mechanisms is used. Cryptography is one of the most important tools to protect sensitive Data and
Information. Previously various cryptographic algorithms have been proposed by many cryptographer and mathematician.
Every cryptographic algorithm has its own advantage and disadvantage. Some algorithms are strong but are less efficient
(AES), some algorithm weak but efficient (DES). In proposed system a “Hybrid Algorithm” will be designed to secure
electronic confidential data. This algorithm is designed by using the concept of Fiestel cipher and AES algorithm. A time
and security based comparison is performed between AES, DES and Hybrid Algorithm to check the efficiency and security
of Hybrid algorithm.
