Secure Transmission of Biometric Scan Images Using Data Encryption Standards(DES) Algorithm

Secure Data Transmission Using Steganography and Encryption Technique

With the spread of digital data around the world through the internet, the security of the data has raised a concern to the people. Many methods are coming up to protect the data from going into the hands of the unauthorized person. Steganography and cryptography are two different techniques for data security. The main purpose in cryptography is to make message concept unintelligible, while ste...

A New Fast Data Encryption Algorithm (FDE)

A stack-based chaotic algorithm for encryption of colored images

In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...

Wireless Transmission of Big Data Using Novel Secure Algorithm

This paper presents a novel algorithm for secure, reliable and flexible transmission of big data in two hop wireless networks using cooperative jamming scheme. Two hop wireless networks consist of source, relay and destination nodes. Big data has to transmit from source to relay and from relay to destination by deploying security in physical layer. Cooperative jamming scheme determines transmis...

Generate an Encryption Key by using Biometric Cryptosystems to secure transferring of Data over a Network

Our modern day era faces an inevitable problem of securing our most integrated data and messages. The chief problem is to protect our data in a unique way that could only be worked upon by the sender and the recipient. Most of the traditional techniques probably in-use today, emphasizes on keys that are generated by generic function, algorithms or in random key generators. But question remains ...
