Development of a GUI for Hybrid (DES-RSA) Data Encryption and Decryption for Transmission of Biomedical Data

Most biomedical data are strictly confidential, hence the need to protect them from an unauthorized party. We had earlier developed and implemented a hybrid cryptography technique that uses a combination of Data Encryption Standard (DES) and Rivest Shamir Adleman (RSA) Algorithms. The DES algorithm was used to encrypt the data while the RSA algorithm was used to transfer DES secret key securely. This paper presents the development of a graphical user interface (GUI) for the developed hybrid technique. The interface was implemented in C#. The developed hybrid technique provides higher throughput, better encryption speed, and CPU power consumption usage.
