Fast Data Encryption (FDE) is a new symmetric block cipher which has a DES-like structure. FDE has been designed with an increased key length, increased key scheduling complexity and an improved round function which can be executed in parallel. FDE uses eight Substitution Boxes (S-boxes) in the round function to provide confusion. In this paper, we present the FDE structure and an algorithm to construct a set of strong S-boxes. Eight suitable S-boxes from this set are suggested for use with FDE.
