Collisions originally reported in 2004, [13] followed up by cryptanalysis paper in 2005. [19] RadioGatún: Up to 2 608 [20] 2 704: 2008-12-04 For a word size w between 1-64 bits, the hash provides a security claim of 2 9.5w. The attack can find a collision in 2 11w time. [21] RIPEMD-160 2 80: 48 of 80 rounds (2 51 time) 2006 Paper. [22] SHA-0: ...
The MD construction is inherently sequential. There is a parallel algorithm [13] which constructs a collision-resistant hash function from a collision-resistant compression function. The hash function PARSHA-256 [14] was designed using the parallel algorithm and the compression function of SHA-256.
In hash tables, since hash collisions are inevitable, hash tables have mechanisms of dealing with them, known as collision resolutions. Two of the most common strategies are open addressing and separate chaining. The cache-conscious collision resolution is another strategy that has been discussed in the past for string hash tables.
Authorities have identified the five people killed in a fiery collision between a school bus and semitruck on a highway in rural Illinois, including a young brother and sister, another 3-year-old ...
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [3] [4] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
A semi-truck carrying thousands of gallons of a toxic substance crashed in southern Illinois, and the multi-vehicle accident killed five people and left five seriously injured, officials said on ...

And while wrong-way collisions make up a fraction of all car crashes — 0.01% of 1.05 million to be exact — they are 40 times more likely to end in death, Bruning said.
