A Symmetric Encription Scheme for Electronic Data Exchange for Edge Medical Devices in a Dew-Fog Computing Environment

Abstract

Electronic data exchange among edge medical devices often comes with concerns, as data to be transmitted are sensitive and there is the need to protect these valuable information assets to maintain the data integrity and confidentiality. In this paper we propose a scheme that allows edge devices to share medical data securely in a dew-fog computing environment using an AES symmetric encryption scheme of a key length 512-bit and by the hashing of the chosen key using SHA-256 to enhance the security of electronic exchanges. � 2019 IEEE.
