The Art of Guessing in Combined Side-Channel Collision Attacks
MDCCF distinguisher voting collision voting
2019/6/13
Recent combined collision attacks have shown promising results for exploiting side-channel leakage information from both divide-and-conquer and analytical distinguishers. However, divide-and-conquer d...
On the Complexity of Collision Resistant Hash Functions: New and Old Black-Box Separations
Collision Resistance Statistical Zero Knowledge Black box separations
2019/6/12
The complexity of collision-resistant hash functions has been long studied in the theory of cryptography. While we often think about them as a Minicrypt primitive, black-box separations demonstrate th...
New Semi-Free-Start Collision Attack Framework for Reduced RIPEMD-160
hash function RIPEMD-160 freedom degree utilization
2019/6/10
RIPEMD-160 is a hash function published in 1996, which shares similarities with other hash functions designed in this time-period like MD4, MD5 and SHA-1. However, for RIPEMD-160, no (semi-free-start)...
An Efficient and Compact Reformulation of NIST Collision Estimate Test
IID Non-IID Min Entropy
2019/5/14
In this paper we give an efficient and compact reformulation of NIST collision estimate test given in SP-800 90B. We correct an error in the formulation of the test and show that the test statistic ca...
Horizontal Collision Correlation Attack on Elliptic Curves
side-channel analysis elliptic curves implementations ECDSA
2019/4/1
Elliptic curves based algorithms are nowadays widely spread among embedded systems. They indeed have the double advantage of providing efficient implementations with short certi cates and of being rel...
Distributional Collision Resistance Beyond One-Way Functions
statistically hiding commitments distributional collision resistance
2019/2/27
Distributional collision resistance is a relaxation of collision resistance that only requires that it is hard to sample a collision (x,y) where x is uniformly random and y is uniformly random conditi...
Full Collision Attack: Pushing the Limits of Exhaustible Key Spaces
FCA full collision group collision attack
2019/1/9
Recovering keys efficiently from far beyond exhaustible candidate spaces is a meaningful but very challenging topic in Side-Channel Attacks (SCA). Recent methods often utilize collision optimizations ...
Finding Collisions in a Quantum World: Quantum Black-Box Separation of Collision-Resistance and One-Wayness
post-quantum cryptography one-way permutation one-way trapdoor permutation
2018/11/12
Since the celebrated work of Impagliazzo and Rudich (STOC 1989), a number of black-box impossibility results have been established. However, these works only ruled out classical black-box reductions a...
In this paper, we re-consider the connecting techniques to find colliding messages, which is achieved by connecting the middle part with the initial part. To obtain the best position of middle part, w...
Better Than Advertised: Improved Collision-Resistance Guarantees for MD-Based Hash Functions
hash functions MD transform SHA
2018/6/25
The MD transform that underlies the MD and SHA families iterates a compression function hh to get a hash function HH. The question we ask is, what property X of hh guarantees collision resistance (CR)...
