A novel approach for data encryption and decryption using feal algorithm in healthcare environment

Fast Encipher Algorithm (FEAL) is an encryption/decryption technique used for the images and files which are used in healthcare environments. An existing FEAL algorithm is used to generate keys based on XAND operation. The generated key is not more secure because it is very easy to hack the content. In this paper, a proposed FEAL algorithm is used for encryption/decryption technique in which generate keys based on stochastic geometry. For instance, in the medical field the report of the patient can able to make secure by using proposed FEAL Algorithm. By using a proposed FEAL algorithm, the original image or text, converts into Ciphertext or an image which is decrypted by using a key. The generation of key based on stochastic geometry is more secure compare to the existing FEAL algorithm. Comparing to existing algorithm, the proposed algorithm is more secure and not easily hack by eavesdroppers. © 2017, Institute of Advanced Scientific Research, Inc. All rights reserved.
