New Semi-Free-Start Collision Attack Framework for Reduced RIPEMD-160
hash function RIPEMD-160 freedom degree utilization
font style='font-size:12px;'>
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)...
Full Collision Attack: Pushing the Limits of Exhaustible Key Spaces
FCA full collision group collision attack
font style='font-size:12px;'>
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 ...
Efficient Collision Attack Frameworks for RIPEMD-160
RIPEMD-160 collision hash function
font style='font-size:12px;'>
2018/7/9
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...

2018/5/28
In this paper, we propose a new cryptanalysis method to mount collision attack on RIPEMD-160. Firstly, we review two existent cryptanalysis methods to mount (semi-free-start) collision attack on MD-SH...
Fast Near Collision Attack on the Grain v1 Stream Cipher
Cryptanalysis Stream ciphers Grain
font style='font-size:12px;'>
2018/2/9
Modern stream ciphers often adopt a large internal state to resist various attacks, where the cryptanalysts have to deal with a large number of variables when mounting state recovery attacks. In this ...

AES Side Channel Attacks
font style='font-size:12px;'>
2017/11/13
Side Channel Attacks are an important attack vector on secure AES implementations. The Correlation-Enhanced Power Analysis Collision Attack by Moradi et al. [13] is a powerful collision attack that ex...

hash functions SHA-3 candidate Gr鴖tl
font style='font-size:12px;'>
2016/1/23
In this article, we describe a novel collision attack for up to 5 rounds of the Gr鴖tl hash function. This significantly improves upon the best previously published results on 3 rounds. By using a ne...
