... hen unauthorized access to data and devices is allowed in the healthcare setting. Transmitting data safely requires that the parties involved maintain the confidentiality of the data they are exchanging. For the protection of Internet of Things data, we proposed using a Lightweight Block Cipher based on a Substitution and Permutation Network (SPN). A block cipher for Internet of Things data security based on the Feistel structure has been created. To protect the information coming from the Internet of Things, develop a hybrid algorithm for generating one-time-use passwords.
