“…It did not provide any specific instantiation or implementation. Subsequent to [37], the constructions AEZ [25] and FMix [7] proposed single key TESs using only the encryption function of the block cipher. FMix is a sequential scheme while AEZ is parallelisable.…”

“…As mentioned earlier, the conceptual possibility of constructing a TES from a PRF (and hence using only the encryption function of a block cipher) has been suggested earlier [37]. The constructions AEZ [25] and FMix [7] are also TESs constructed from a PRF. The possibility of constructing TESs from stream ciphers has been considered [37].…”

“…From the descriptions of FAST.Encrypt K (T, P ) and FAST.Decrypt K (T, C) in Table 1, the following two facts are easy to verify. For K ∈ K, T ∈ T and P ∈ P, FAST.Decrypt K (T, FAST.Encrypt K (T, P )) = P ; (7) len (FAST.Encrypt K (T, P )) = len(P ). (8) From (7), it follows that the decryption function of FAST is the inverse of the encryption function, while (8) shows that the length of the ciphertext produced by the encryption function is equal to the length of the plaintext.…”

“…More importantly, this work presents detailed software implementations of different instantiations of FAST and thereby actually demonstrates the advantages of the new proposal in comparison to the previous works. Another class of block cipher based TESs such as CMC [23], EME [24,20] (the scheme EME2 is essentially EME * [20]), AEZ [25] and FMix [7] essentially uses several layers of encryption using a mode of operation of a block cipher. CMC, EME and FMix use two layers of encryption whereas AEZ uses three layers of encryption.…”

This work introduces FAST which is a new family of tweakable enciphering schemes. Several instantiations of FAST are described. These are targeted towards two goals, the specific task of disk encryption and a more general scheme suitable for a wide variety of practical applications. A major contribution of this work is to present detailed and careful software implementations of all of these instantiations. For disk encryption, the results from the implementations show that FAST compares very favourably to the IEEE disk encryption standards XCB and EME2 as well as the more recent proposal AEZ. FAST is built using a fixed input length pseudo-random function and an appropriate hash function. It uses a single-block key, is parallelisable and can be instantiated using only the encryption function of a block cipher. The hash function can be instantiated using either the Horner's rule based usual polynomial hashing or hashing based on the more efficient Bernstein-Rabin-Winograd polynomials. Security of FAST has been rigorously analysed using the standard provable security approach and concrete security bounds have been derived. Based on our implementation results, we put forward FAST as a serious candidate for standardisation and deployment.

Through pseudorandom permutation, tweakable enciphering schemes (TES) constitute block cipher modes of operation which perform length-preserving computations. The state-of-the-art research has focused on different aspects of TES, including implementations on hardware [field-programmable gate array (FPGA)/ application-specific integrated circuit (ASIC)] and software (hard/soft-core microcontrollers) platforms, algorithmic security, and applicability to sensitive, security-constrained usage models. In this article, we propose efficient approaches for protecting such schemes against natural and malicious faults. Specifically, noting that intelligent attackers do not merely get confined to injecting multiple faults, one major benchmark for the proposed schemes is evaluation toward biased and burst fault models. We evaluate a variant of TES, i.e., the Hash-Counter-Hash scheme, which involves polynomial hashing as other variants are either similar or do not constitute finite field multiplication which, by far, is the most involved operation in TES. In addition, we benchmark the overhead and performance degradation on the ASIC platform. The results of our error injection simulations and ASIC implementations show the suitability of the proposed approaches for a wide range of applications including deeply embedded systems.
