Project Title: Implementation of an Application to Secure Personal Data Using Enhanced DES
Semester: 2 2014
Committe Chair: Dr. Mario Garcia

Committee Member 2: Dr. David Thomas
Project Description: Security is one of the important features in the field of communication system, specifically on a network and the internet. Developing applications using data encryption techniques for ensuring personal data security in network communication plays a significant role in the field of cryptography. Several block cipher techniques ensure security for personal data, when shared on the internet, like Caesar Cipher, Monoalphabetic Cipher, Polyalphabetic Cipher, Columnar Transposition, Data Encryption Standard (DES), and Advanced encryption Standard (AES). The project provides a platform for the users to upload multiple files, along with file sharing and file downloading. The concept of Enhanced DES in encrypting and decrypting the data is practiced. The contribution done in the project is modification over the traditional DES algorithm. The transposition technique is added before the DES algorithm, thereby adding layer of security, as any attack made on the cipher text needs to break the DES algorithm followed by the transposition technique, which implies double security. The proposed report concerning the features and functionality of enhances DES system in securing personal data.
