On the Boomerang Uniformity of some Permutation Polynomials
Vectorial Boolean functions Boomerang uniformity Boomerang connectivity table
2019/8/2
The boomerang attack, introduced by Wagner in 1999, is a cryptanalysis technique against block ciphers based on differential cryptanalysis. In particular it takes into consideration two differentials,...
Cryptanalysis of an Ultra lightweight Authentication Scheme based on Permutation Matrix Encryption for Internet of Vehicles
IoV security analysis matrix encryption
2019/7/23
Internet of Things (IoT) has various applications such as healthcare, supply chain, agriculture, etc. Using the Internet of Vehicles(IoV) to control traffic of the cities is one of the IoT application...

Permutation Polynomials Differential Uniformity Boomerang Uniformity
2019/7/8
The differential uniformity, the boomerang uniformity, and the extended Walsh spectrum etc are important parameters to evaluate the security of S(substitution)-box. In this paper, we introduce efficie...
Iterated Truncated Differential for Internal Keyed Permutation of FlexAEAD
FlexAEAD Distinguisher Iterated Differential
2019/5/23
In this draft, the internal keyed permutation of FlexAEAD has been analysed. In our analysis, we have first reported an iterated truncated differential for one round which holds with a probability of ...
On the Streaming Indistinguishability of a Random Permutation and a Random Function
Streaming algorithm time-memory tradeoff switching lemma
2019/4/23
An adversary with SS bits of memory obtains a stream of QQ elements that are uniformly drawn from the set {1,2,…,N}{1,2,…,N}, either with or without replacement. This corresponds to sampling QQ elemen...
Recently, the NIST launched a competition for lightweight cryptography and a large number of ciphers are expected to be studied and analyzed under this competition. Apart from the classical security, ...
Key-dependent cube attack on reduced Frit permutation in Duplex-AE modes
Frit Duplex authenticated encryption mode Key-dependent cube attack
2019/2/25
Frit is a new lightweight 384-bit cryptographic permutation proposed by Simon et al., which is designed for resisting fault injection and performs competitively in both hardware and software. Dobrauni...
New Results about the Boomerang Uniformity of Permutation Polynomials
Finite Field Boomerang Connectivity Table Boomerang Uniformity
2019/1/29
In EUROCRYPT 2018, Cid et al. introduced a new concept on the cryptographic property of S-boxes: Boomerang Connectivity Table (BCT for short) for evaluating the subtleties of boomerang-style attacks. ...
Wide Tweakable Block Ciphers Based on Substitution-Permutation Networks: Security Beyond the Birthday Bound
substitution-permutation networks tweakable block ciphers domain extension of block ciphers
2018/5/28
Substitution-Permutation Networks (SPNs) refer to a family of constructions which build a wnwn-bit (tweakable) block cipher from nn-bit public permutations. Many widely deployed block ciphers are part...
A Chosen Plaintext Attack on Offset Public Permutation Mode
symmetric cryptography block cipher mode of operation authenticated encryption
2018/4/20
Offset Public Permutation Mode (OPP) by Granger et al. is a one-pass authenticated encryption scheme supporting associated data (AEAD scheme). Leveraging an error in analysis of the scheme, a chosen p...
GGH15 Beyond Permutation Branching Programs: Proofs, Attacks, and Candidates
Graded encodings indistinguishability obfuscation
2018/4/19
We present new constructions of private constrained PRFs and lockable obfuscation, for constraints (resp. functions to be obfuscated) that are computable by general branching programs. Our constructio...

Secret-Key Cryptography Generic Group Model Non-Uniformity
2018/3/5
The random-permutation model (RPM) and the ideal-cipher model (ICM) are idealized models that offer a simple and intuitive way to assess the conjectured standard-model security of many important symme...
We study instantiating the random permutation of the block-cipher mode of operation IAPM (Integrity-Aware Parallelizable Mode) with the public random permutation of Keccak, on which the draft standard...
A Unified Framework for Trapdoor-Permutation-Based Sequential Aggregate Signatures
Aggregate signatures trapdoor permutations ideal cipher model
2018/1/19
We give a framework for trapdoor-permutation-based sequential aggregate signatures (SAS) that unifies and simplifies prior work and leads to new results. The framework is based on ideal ciphers over l...
