LSH (hash Function)
LSH is a cryptographic hash function designed in 2014 by South Korea to provide integrity in general-purpose software environments such as Personal computer, PCs and smart devices. LSH is one of the cryptographic algorithms approved by the Korean Cryptographic Module Validation Program (KCMVP). And it is the national standard of South Korea (KS X 3262). Specification The overall structure of the hash function LSH is shown in the following figure. The hash function LSH has the wide-pipe Merkle-Damgård structure with one-zeros padding. The message hashing process of LSH consists of the following three stages. # ''Initialization'': #* One-zeros padding of a given bit string message. #* Conversion to 32-word array message blocks from the padded bit string message. #* Initialization of a chaining variable with the initialization vector. # ''Compression'': #* Updating of chaining variables by iteration of a compression function with message blocks. # ''Finalization'': #* Generati ...

Locality-sensitive Hashing
In computer science, locality-sensitive hashing (LSH) is a fuzzy hashing technique that hashes similar input items into the same "buckets" with high probability. (The number of buckets is much smaller than the universe of possible input items.) Since similar items end up in the same buckets, this technique can be used for data clustering and nearest neighbor search. It differs from conventional hashing techniques in that hash collisions are maximized, not minimized. Alternatively, the technique can be seen as a way to reduce the dimensionality of high-dimensional data; high-dimensional input items can be reduced to low-dimensional versions while preserving relative distances between items. Hashing-based approximate nearest-neighbor search algorithms generally use one of two main categories of hashing methods: either data-independent methods, such as locality-sensitive hashing (LSH); or data-dependent methods, such as locality-preserving hashing (LPH).

Headquarters Ship
During the Second World War, the Royal Navy The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom ... commissioned several headquarters ships (sometimes referred to as Landing Ship Headquarters), which were responsible for communication between aircraft, ships and shore during amphibious operations. The first such recognised ship was . During the Second World War, four Landing Ships Headquarters (Large) (or LSH(L)s) were commissioned into the Royal Navy. * - formerly the MV ''Bulolo'' requisitioned from Burns Philps. Served as the LSH for Gold Beach, Gold during the Normandy Landings. * - formerly the French passenger liner MV ''Charles Plumier'' and seized by the Royal Navy at Gibraltar. Served as the LSH for Sword Beach, Sword during the Normandy Landings. * HMS Hilary (1940), HMS ''H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
