A General Proof Framework for Recent AES Distinguishers
AES Distinguisher Subspace Trail Cryptanalysis
2019/2/26
In this paper, a new framework is developed for proving and adapting the recently proposed multiple-of-8 property and mixture-differential distinguishers. The above properties are formulated as immedi...
MILP Method of Searching Integral Distinguishers Based on Division Property Using Three Subsets
Division property using three subsets Integral distinguisher MILP
2018/12/11
Division property is a generalized integral property proposed by Todo at EUROCRYPT 2015, and then conventional bit-based division property (CBDP) and bit-based division property using three subsets (B...
Towards Key-Dependent Integral and Impossible Differential Distinguishers on 5-Round AES
AES Key-Dependent Integral
2018/8/10
Reduced-round AES has been a popular underlying primitive to design new cryptographic schemes and thus its security including distinguishing properties deserves more attention. At Crypto'16, a key-dep...
The division property method is a technique to determine integral distinguishers on block ciphers. While the complexity of finding these distinguishers is higher, it has recently been shown that MILP ...
Categorising and Comparing Cluster-Based DPA Distinguishers
side-channel analysis, DPA, machine learning
2017/8/10
Side-channel distinguishers play an important role in differential power analysis, where real world leakage information is compared against hypothetical predictions in order to guess at the underlying...
AES is often considered as a target of such analyses, simply because AES or its building blocks are used in many settings that go beyond classical encryption. The most recent known-key model of Gilber...
In this work we show the existence of special sets of inputs for which the sum of the images under SHA3 exhibits a symmetric property. We develop an analytical framework which accounts for the existen...
Applying MILP Method to Searching Integral Distinguishers Based on Division Property for 6 Lightweight Block Ciphers
MILP division property integral cryptanalysis
2016/12/10
Division property is a generalized integral property proposed by Todo at EUROCRYPT 2015, and very recently, Todo et al. proposed bit-based division property and applied to SIMON32 at FSE 2016. However...
A Key to Success -- Success Exponents for Side-Channel Distinguishers
Success ExponentsSide-Channel Distinguishers
2016/12/8
The success rate is the classical metric for evaluating the performance of side-channel attacks. It is generally computed empirically from measurements for a particular device or using simulations. Cl...
Chosen-Key Distinguishers on 12-Round Feistel-SP and 11-Round Collision Attacks on Its Hashing Modes(Full version)
Block cipher Feistel-SP Chosen-key
2016/5/26
Since Knudsen and Rijmen proposed the known-key attacks in ASIACRYPT 2007, the open-key model becomes more and more popular. As the other component of the open-key model, chosen-key model was applied ...
A Theoretical Study of Kolmogorov-Smirnov Distinguishers, Side-Channel Analysis vs. Differential Cryptanalysis
Side-channel distinguisher Confusion coefficient Kolmogorov- Smirnov analysis
2016/1/26
In this paper, we carry out a detailed mathematical study of
two theoretical distinguishers based on the Kolmogorov-Smirnov (KS)
distance. This includes a proof of soundness and the derivation of cl...
Good is Not Good Enough: Deriving Optimal Distinguishers from Communication Theory
Side-channel analysis distinguisher communication channel
2016/1/8
We find mathematically optimal side-channel distinguishers
by looking at the side-channel as a communication channel. Our methodology
can be adapted to any given scenario (device, signal-to-noise ra...
From Related-Key Distinguishers to Related-Key-Recovery on Even-Mansour Constructions
Even-Mansour；related-key attacks, Pr┆st-OTR
2016/1/4
We show that a distinguishing attack in the related key model on an EvenMansour
block cipher can readily be converted into an extremely efficient key recovery attack.
Concerned ciphers include in pa...
New Distinguishers for Reduced Round Trivium and Trivia-SC using Cube Testers
Cryptanalysis Cube Tester Stream Cipher
2016/1/3
In this paper we experiment with cube testers on reduced round Trivium that can act
as a distinguisher. Using heuristics, we obtain several distinguishers for Trivium running more than
800 rounds (m...
Masks will Fall Off -- Higher-Order Optimal Distinguishers
security analysis cryptographic devices
2015/12/30
Higher-order side-channel attacks are able to break the security
of cryptographic implementations even if they are protected with
masking countermeasures. In this paper, we derive the best possible
