FPE scheme based on k-splits Feistel network

The construction features and discipline of Feistel network-based FPE (format-preserving encryption) schemes were analyzed. Considering on the problem that 2-splits Feistel networks-based FPE cipher's block size was in narrow range, a type-2 Feistel network-based FPE scheme, which was suitable...

Summary:The construction features and discipline of Feistel network-based FPE (format-preserving encryption) schemes were analyzed. Considering on the problem that 2-splits Feistel networks-based FPE cipher's block size was in narrow range, a type-2 Feistel network-based FPE scheme, which was suitable for constructing FPE cipher with scalable block size, was presented. Experiment show that type-2 Feistel network is able to use small-scaled pseudorandom function to construct cipher with scalable block size and that is practical.
