Modeling Memory Faults in Signature and Encryption Schemes
fault attacks security model fault resilience deterministic signatures
2019/9/19
Memory fault attacks, inducing errors in computations, have been an ever-evolving threat to cryptographic schemes since their discovery for cryptography by Boneh et al. (Eurocrypt 1997). Initially req...
Low Weight Discrete Logarithms and Subset Sum in 20.65n with Polynomial Memory
Low weight dlog subset sum representations Nested Rho
2019/8/19
We propose two polynomial memory collision finding algorithms for the low Hamming weight discrete logarithm problem in any abelian group GG. The first one is a direct adaptation of the Becker-Coron-Jo...
Low-Memory Attacks against Two-Round Even-Mansour using the 3-XOR Problem
Even-Mansour Cryptanalysis 3-XOR
2019/8/19
The iterated Even-Mansour construction is an elegant construction that idealizes block cipher designs such as the AES. In this work we focus on the simplest variant, the 2-round Even-Mansour construct...
Improved Low-Memory Subset Sum and LPN Algorithms via Multiple Collisions
time-memory trade-off representations parallel collision search
2019/7/15
For enabling post-quantum cryptanalytic experiments on a meaningful scale, there is a strong need for low-memory algorithms. We show that the combination of techniques from representations, multiple c...
On designing secure small-state stream ciphers against time-memory-data tradeoff attacks
Stream cipher Ultra-lightweight Small-state
2019/6/10
A new generation of stream ciphers, small-state stream ciphers (SSCs), was born in 2015 with the introduction of the Sprout cipher. The new generation is based on using key bits not only in the initia...
Memory-Efficient High-Speed Implementation of Kyber on Cortex-M4
ARM Cortex-M4 number-theoretic transform lattice-based cryptography
2019/5/21
This paper presents an optimized software implementation of the module-lattice-based key-encapsulation mechanism Kyber for the ARM Cortex-M4 microcontroller. Kyber is one of the round-2 candidates in ...
Tight Time-Memory Trade-offs for Symmetric Encryption
provable security time-memory trade-offs
2019/3/6
Concrete security proofs give upper bounds on the attacker's advantage as a function of its time/query complexity. Cryptanalysis suggests however that other resource limitations - most notably, the at...

2019/1/2
Memory-constrained devices, including widely used smart cards, require resisting attacks by the quantum computers. Lattice-based encryption scheme possesses high efficiency and reliability which could...
Data-Independent Memory Hard Functions: New Attacks and Stronger Constructions
Memory Hard Function Depth-Robust Graph Sustained Space Complexity
2018/11/7
Data-Independent Memory-hard functions (iMHFs) are a key cryptographic primitive underlying the design of moderately expensive password hashing algorithms and egalitarian proofs of work that are resis...
Laser-induced Single-bit Faults in Flash Memory: Instructions Corruption on a 32-bit Microcontroller

AES Mixture Differential
2018/6/5
Determining the security of AES is a central problem in cryptanalysis, but progress in this area had been slow and only a handful of cryptanalytic techniques led to significant advancements. At Eurocr...
In Crypto 2017, Auerbach et al. initiated the study on memory-tight reductions and proved two negative results on the memory-tightness of restricted black-box reductions from multi-challenge security ...
