This paper presents CONCRETE (Commit-Encrypt-Send-the-Key) a new Authenticated Encryption mode that offers CIML2 security, that is, ciphertext integrity in the presence of nonce misuse and side-channe...
Tweakable block cipher (TBC), a stronger notion than standard block ciphers, has wide-scale applications in symmetric-key schemes. At a high level, it provides flexibility in design and (possibly) bet...
Traditionally, countermeasures against physical attacks are integrated into the implementation of cryptographic primitives after the algorithms have been designed for achieving a certain level of cryp...
Strong Pseudo-random Permutations (SPRPs) are important for various applications. In general, it is desirable to base an SPRP on a single-keyed primitive for minimizing the implementation costs. For c...
A new approach to invariant subspaces and nonlinear invariants is developed. This results in both theoretical insights and practical attacks on block ciphers. It is shown that, with minor modification...
SFN is a lightweight block cipher designed to be compact in hardware environment and also efficient in software platforms. Compared to the conventional block ciphers that are either Feistel or Substit...
In a world heavily loaded by information, there is a great need for keeping specifi c information secure from adversaries. The rapid growth in the research fi eld of lightweight cryptography can be se...
In this paper we improve Wu and Wang's method for finding impossible differentials of block cipher structures. This improvement is more general than Wu and Wang's method that it can find more impossib...
Block cipher modes of operation provide a way to securely encrypt using a block cipher. The main factors in analyzing modes of operation are the level of security achieved (chosen-plaintext security, ...
We propose a new mode of operation called ZMAC allowing to construct a (stateless and deterministic) message authentication code (MAC) from a tweakable block cipher (TBC). When using a TBC with n-bit ...
Defined in the standard GOST 28147-89, GOST is a Soviet and Russian government standard symmetric-key block cipher. GOST has the 64-bit block size and a key length of 256 bits. It is a Feistel network...
QARMA is a recently published lightweight tweakable block cipher, which has been used by the ARMv8 architecture to support a software protection feature. In this paper, using the method of MITM, we gi...
In this paper, we analyzed an extreme case of lightweight block cipher design in terms of security and efficiency. To do this, we proposed ELiF block cipher family which has one of the smallest hardwa...
The huge time and memory complexities of utilizing bit-based division property, which was first presented by Todo and Morri at FSE 2016, bothered cryptographers for quite some time and it had been sol...
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and related-tweake impossib...
