Abstract:
A format-preserving cipher including an encryption and a decryption scheme supporting non-linear access to input data by allowing the selection of portions of data from a potentially larger dataset to be encrypted, thus avoiding a necessarily sequential access into the input plaintext data. The cipher first defines a forward mapping from the allowable ciphertext values to an integer set of the number of such allowable ciphertext values, and a corresponding reverse mapping. It also supports exclusion of a certain set of characters from the ciphering process. An encryption algorithm is provided that encrypts the input plaintext data while preserving its original format and length, and a corresponding decryption algorithm is provided. The cipher advantageously embodies the encryption and decryption of multi-byte values, composite datasets, and credit card numbers, thus fitting a variety of industrial needs.

Claim (Index 2):
The method of  claim 1 , where said data to be ciphered is binary data.
