  Abstract

When encrypted, block encryption increases in length by a factor of block size multiplication. Therefore, it suffers from a drawback that data encryption with fixed length and structure is challenging, such as that in the IoT and connected cars. Format preserving encryption can efficiently encrypt by solving the problem of block ciphers. Meanwhile, format preserving encryption FEA is a domestically developed format that preserves encryption; it is encrypted/decrypted in the Rank function, TBC encrypt, and Unrank function stages; but in its original paper and standard, the Rank function is not defined, this is designed to be implemented directly by the user. This study implements the entire process of FEA through direct implementation of the Rank function. We investigated whether the implemented FEA is normally encrypted/decrypted, and confirmed that the encryption/decryption speed is faster compared to the US NIST standard format for preserving encryption.
