In CRYPTO 2017, Mennink and Neves showed almost n-bit security for a dual version of EWCDM. In this paper we describe a birthday attack on this construction which violates their claim.
A Lightweight Hash Function Resisting Birthday Attack and Meet-in-the-middle Attack
Lightweight hash function Compression algorithm
2014/3/12
In this paper, to match a lightweight digital signing scheme of which the length of modulus is between 80 and 160 bits, a lightweight hash function called JUNA is proposed. It is based on the intracta...

Let r, B and w be positive integers. Let C be a linear code of length Bw and subspace of Fr . The k-regular-decoding problem is to find 2 a nonzero codeword consisting of w length-B blocks with Hammin...
FSBday:Implementing Wagner’s generalized birthday attack against the SHA-3 candidate FSB
SHA-3 Birthday FSB – Wagner
2009/6/23
The hash function FSB is one of the candidates submitted
to NIST’s competition to find the new standard hash function, SHA-3.
The compression function of FSB is based on error correcting codes. In

How to Launch A Birthday Attack Against DES
DES Differential cryptanalysis Linear cryptanalysis
2009/6/5
We present a birthday attack against DES. It is entirely based on the relationship
Li+1 = Ri and the simple key schedule in DES. It requires about 216 ciphertexts of the same
R16, encrypted by the s...
We analyze a generic birthday attack where distinct inputs to some function f are
selected until two of the inputs map through f to the same output, meaning that the attack has
succeeded. We give ti...
General Distinguishing Attacks on NMAC and HMAC with Birthday Attack Complexity
NMAC HMAC Distinguishing Attack Birthday Attack
2009/1/5
Kim et al. [4] and Contini et al. [3] studied on the security of
HMAC and NMAC based on HAVAL, MD4, MD5, SHA-0 and SHA-1.
Especially, they considered the distinguishing attacks. However, they did
n...
