, 2009 We provide a collision attack and preimage attacks on the MDC-2 construction, which is a method (dating back to 1988) of turning an n -bit block cipher into a 2n -bit hash function. The collision attack is the first below the birthday bound to be described for MDC-2 and, with n = 128, it has complexity 2124.5, which is to be compared to the birthday ...

Serangan Kolisi dan Second Preimage Terhadap Skema Modifikasi MDC-2 Berbasis PRESENT
Info Kripto, 2023 MDC-2 merupakan salah satu bentuk skema double-length hash function yang bertujuan untuk memfasilitasi jaminan integritas data. Skema ini menggunakan input berupa dua operasi block cipher per blok dari input hash dengan hanya menggunakan input berupa pesan tanpa kunci. Ide konstruksi penggunaan block cipher sebagai komponen utama fungsi hash diharapkan

Systemic immune activation in HIV infection is associated with decreased MDC responsiveness to TLR ligand and inability to activate naive CD4 T-cells. [PDF]
PLoS ONE, 2011 HIV infection is characterized by ineffective anti-viral T-cell responses and impaired dendritic cell (DC) functions, including response to Toll-Like Receptor (TLR) ligands.

Binary brown dwarfs in the galactic halo? [PDF]
, 1998 Microlensing events towards the Large Magellanic Cloud entail that a sizable fraction of dark matter is in the form of MACHOs (Massive Astrophysical Compact Halo Objects), presumably located in the halo of the Galaxy.

On the Design of Secure and Fast Double Block Length Hash Functions [PDF]
, 2008 In this work the security of the rate-1 double block length hash functions, which based on a block cipher with a block length of n-bit and a key length of 2n-bit, is reconsidered.
