Özet

In the classical Feistel structure the usage of alternating keys makes the cipher insecure against the related key attacks. In this work, we propose a new block cipher scheme, AKF, based on a Feistel structure with alternating keys but resistant against related key attacks. AKF leads constructions of lightweight block ciphers suitable for resource restricted devices such as RFID tags and wireless sensor nodes.
