Cryptanalysis of MDC-2 [PDF]

open access: bronzeInternational Conference on the Theory and Application of Cryptographic Techniques, 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 ...

The Collision Intractability of MDC-2 in the Ideal-Cipher Model [PDF]

open access: bronzeIACR Cryptology ePrint Archive, 2007
We provide the first proof of security for MDC-2, the most well-known construction for turning an n-bit blockcipher into a 2n-bit cryptographic hash function. Our result, which is in the ideal-cipher model, shows that MDC-2, when built from a blockcipher having blocklength and keylength n, has security much better than that delivered by any hash ...

Serangan Kolisi dan Second Preimage Terhadap Skema Modifikasi MDC-2 Berbasis PRESENT

open access: diamondInfo 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

Mejoramiento del asfalto 60/70 y la mezcla asfáltica mdc-2 con nanotubos de carbono obtenidos a partir de metano vía catalítica [PDF]

open access: gold, 2022
Se realizó un diseño de experimentos para el proceso de descomposición catalítica de metano, en el que se evaluó la temperatura (600, 700 y 800 ºC), el tipo de catalizador y el tiempo de reacción (1, 2 y 3 h). La variable de selección fue el peso bruto de los NTC obtenidos.

Chitosan Scaffolds from Crustacean and Fungal Sources: A Comparative Study for Bone-Tissue-Engineering Applications

open access: yesBioengineering
Chitosan (CS), a biopolymer, holds significant potential in bone regeneration due to its biocompatibility and biodegradability attributes. While crustacean-derived CS is conventionally used in research, there is growing interest in fungal-derived CS for ...
