“…Regarding the performance of FPE encryption methods, some studies have been done, however they are mainly related to software implementations [14], [16]- [18]. For performance benefits, a hardware implementation could be considered as in [13], [19] or [20]. A hardware implementation of an FPE stream cipher could be advantageous for that cases where a high encryption rate is important and the plaintext format preservation is mandatory.…”

A New Method for Format Preserving Encryption in High-Data Rate Communications

In some encryption systems it is necessary to preserve the format and length of the encrypted data. This kind of encryption is called FPE (Format Preserving Encryption). Currently, only two AES (Advanced Encryption Standard) modes of operation recommended by the NIST (National Institute of Standards and Technology) are able to implement FPE algorithms, FF1 and FF3. These modes work in an electronic codebook fashion and can be configured to encrypt databases with an arbitrary format and length. However, there are no stream cipher proposals able to implement FPE encryption for high data rate information flows. The main novelty of this work is a new block cipher operation mode proposal to implement an FPE algorithm in a stream cipher fashion. It has been called CTR-MOD and it is based on a standard block cipher working in CTR (Counter) mode and a modulo operation. The confidentiality of this mode is analyzed in terms of its IND-CPA (Indistinguishability under Chosen Plaintext Attack) advantage of any adversary attacking it. Moreover, the encryption scheme has been implemented on an FPGA (Field Programmable Gate Array) and has been integrated in a Gigabit Ethernet interface to test an encrypted optical link with a real high data rate traffic flow. INDEX TERMS FPE (format preserving encryption), stream cipher, FPGA (field programmable gate array), Ethernet.
