TL;DR: A new FPE mode named coding-then-encipher mode was proposed and its operating principle and security were described in detail, and it was pointed out that the key for this mode was finding efficient encode and decode algorithms on domain.
Abstract: FPE(format-preserving encryption) was discussed,and it was shown that how to reduce domain complexity was the direction of designing FPE modes.A new FPE mode named coding-then-encipher mode was proposed and its operating principle and security were described in detail,and it was pointed out that the key for this mode was finding efficient encode and decode algorithms on domain.Furthermore,a scheme under coding-then-encipher mode which can resolve FPE problem in charsn was presented,the encode and decode algorithms were described,and their efficiency were analyzed.

26 Sep 2016TL;DR: In this paper, the authors provide a technological improvement to a cipher by improving data security of format-preserving encryption (FPE), by embedding specific key identifiers for rotating keys directly into ciphertext.
Abstract: Aspects of the disclosure provide a technological improvement to a cipher by improving data security of format-preserving encryption (FPE), by, inter alia, embedding specific key identifiers for rotating keys directly into ciphertext. Aspects of the disclosure relate to methods, computer-readable media, and apparatuses for improving data security in a format-preserving encryption (FPE) context by using specific methods of rotating and identifying the appropriate encryption key from among numerous rotating keys stored in a key data store. Specific to FPE, a plaintext of the data and its corresponding ciphertext of the data remain the same in length/size; yet the methods, computer-readable media, and/or apparatuses disclosed herein permit embedding of an identification of a specific key among the plurality of rotating keys for the particular ciphertext without compromising the technical requirements of FPE.

TL;DR: In this article, the format preserving encryption (FPE) is applied to the received object code, where the FPE is applied separately to a subplurality of instructions in the list of instructions, to generate an encrypted object code comprising a sub-plural of encrypted instructions.
Abstract: Format preserving encryption of object code is disclosed. One example is a system including at least one processor and a memory storing instructions executable by the at least one processor to identify object code to be secured, where the object code comprises a list of instructions, each instruction comprising an opcode and zero or more parameters. A format preserving encryption (FPE) is applied to the received object code, where the FPE is applied separately to a sub-plurality of instructions in the list of instructions, to generate an encrypted object code comprising a sub-plurality of encrypted instructions. An encrypted object code is provided to a service provider, where the encrypted object code comprises the sub-plurality of encrypted instructions, and any unencrypted portions of the object code.
