A Synopsis of Format-Preserving Encryption
نویسنده
چکیده
Format-preserving encryption (FPE) encrypts a plaintext of some specified format into a ciphertext of the same format—for example, encrypting a social-security number into a social-security number. In this survey we describe FPE and review known techniques for achieving it. These include FFX, a recent proposal made to NIST.

Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption
This Recommendation specifies three methods for format-preserving encryption, called FF1, FF2, and FF3. Each of these methods is a mode of operation of the AES algorithm, which is used to construct a round function within the Feistel structure for encryption.
متن کاملNotes on Property - Preserving Encryption
The first type of specialized encryption scheme that can be used in secure outsourced storage we will look at is property-preserving encryption. This is encryption where some desired property of the plaintexts is intentionally leaked by the ciphertexts. The two main examples we will study are deterministic encryption, which preserves the equality property, and order preserving encryption, which...
متن کاملPractical Solutions For Format-Preserving Encryption
Format Preserving Encryption (FPE) schemes encrypt a plaintext into a ciphertext while preserving its format (e.g., a valid social-security number is encrypted into a valid social-security number), thus allowing encrypted data to be stored and used in the same manner as unencrypted data. Motivated by the always-increasing use of cloud-computing and memory delegation, which require preserving bo...

This note describes a theoretical chosen-plaintext attack on the VAES3 mode for format-preserving encryption. VAES3 was specified under the name FF2 in Draft NIST Special Publication 800-38G.
متن کاملSESOS: A Verifiable Searchable Outsourcing Scheme for Ordered Structured Data in Cloud Computing
While cloud computing is growing at a remarkable speed, privacy issues are far from being solved. One way to diminish privacy concerns is to store data on the cloud in encrypted form. However, encryption often hinders useful computation cloud services. A theoretical approach is to employ the so-called fully homomorphic encryption, yet the overhead is so high that it is not considered a viable s...
