TAILIEUCHUNG - A survey of format preserving encryption modes

In this scheme the format of plaintext and ciphertext are same. The three main Format Preserving Encryption modes such as FF1, FF2 and FF3 approved by National Institute of Science and Technology(NIST) are analysed and highlights the differences in performance. | ISSN:2249-5789 S Vidhya, International Journal of Computer Science & Communication Networks,Vol 6(6),255-258 A Survey of Format Preserving Encryption Modes Assistant Professor, Department of Information Technology, KG College of Arts and Science, Coimbatore. Mail-id : Abstract: In the age of big data large amount of sensitive data Most of the encryption algorithms make changes in the are handled through the network. There is a tremendous length and format of the data. In order to store the growth in digital transactions all over the world. Encryption encrypted data, reengineering of database is required. The provides a major part in data security. The encryption application programs involving the database is also expands the length of the data and changes the type of data. changed. The database change approaches are very tedious, The traditional encryption methods require considerable costly process that are error prone. amount of changes in the database as well as the applications developed for the database. In this paper, I analyse special Format Preserving Encryption is a useful tool for kind of encryption that is Format Preserving Encryption. modern cryptographic approaches. It is mainly used for Format Preserving Encryption means encrypting data without encrypting structured data like Social Security Number changing its data type and format. In this scheme the format (SSN), Credit Card Number (CCN) and any data of fixed of plaintext and ciphertext are same. The three main Format Preserving Encryption modes such as FF1, FF2 and FF3 approved by National Institute of Science and Technology(NIST) are analysed and highlights the differences in performance. length. Format Preserving Encryption is an encryption in which cipertext has same format as plaintext. FPE modes are designed for any type of data[1]. An above diagram clearly shows that using FPE 16 digit I. INTRODUCTION credit card number is encrypted .
