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 …

Schemes for FPE enable one to encrypt Social Security numbers (SSNs), credit card
numbers (CCNs), and the like, doing so in such a way that the ciphertext has the same …

Commonly used encryption methods treat the plaintext merely as a stream of bits,
disregarding any specific format that the data might have. In many situations, it is desirable …

Format Preserving Encryption (FPE) schemes encrypt a plaintext into a ciphertext while
preserving its format (eg, a valid social-security number is encrypted into a valid social …

Assume that a symmetric encryption scheme has been deployed and used with a secret key.
We later must change the encryption scheme in a way that preserves the ability to decrypt (a …

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) …

Format-preserving encryption (FPE) encrypts a plaintext of some specified format into a
ciphertext of identical format—for example, encrypting a valid credit-card number into a valid …

The American National Institue for Standards in Technology (NIST) is considering proposals
for several modes of operation for Format Preserving Encryption (FPE). The idea behind …

Format‐preserving encryption (FPE) allows encrypting plaintexts while preserving a specific
format. In Selected Areas in Cryptography 2018, two targeted ciphers were proposed as new …
