Executive Summary

Cryptography is a technique used to transmit data in a secured way through the internet. Encryption is the process of converting information from its original form (called plaintext) into an encoded, unreadable form (called cipher text). Format Preserving Encryption (FPE) refers to a set of techniques for encrypting data such that the cipher text has the same format as the plaintext. A format-preserving encryption scheme is applicable for many real-life applications. FPE is a good encryption scheme that allows for encryption with minimal modifications to the original plain text. The author examine the FPE model constructed by Black and Rogaway.
