Data Encryption Standard (DES) is based on the Feistel block cipher,developed in 1971 by IBM cryptography researcher Horst Feistel. DES uses 16rounds of the Feistel structure. But with the changes in recent years, theinternet is starting to be used more to connect devices to each other. Thesedevices can range from powerful computing devices, such as desktop computersand tablets, to resource constrained devices, When it comes to theseconstrained devices, using a different key for each round cryptographyalgorithms fail to provide necessary security and performance.
