Hiding : A hash function H is …
WebDec 15, 2011 · collision resistance, strong-collision — it is computationally infeasible to find any two distinct inputs x, x' which hash to the same output, i.e., such that h (x) = h (x'). Fact 1: Collision resistance implies 2nd-preimage resistance of hash functions. Fact 2: 2nd-preimage resistance implies preimage resistance. WebAbstract. Recently, some collisions have been exposed for a variety of cryptographic hash functions [20,21] including some of the most widely used today. Many other hash functions using similar constructions can howeverstill beconsidered secure. Nevertheless, thishas drawn attention on the need for new hash function designs.

In cryptography, collision resistance is a property of cryptographic hash functions: a hash function H is collision-resistant if it is hard to find two inputs that hash to the same output; that is, two inputs a and b where a ≠ b but H(a) = H(b). The pigeonhole principle means that any hash function with more inputs than … See more A family of functions {hk : {0, 1} → {0, 1} } generated by some algorithm G is a family of collision-resistant hash functions, if m(k) > l(k) for any k, i.e., hk compresses the input string, and every hk can be computed within … See more • Collision attack • Preimage attack • NIST hash function competition See more Collision resistance is desirable for several reasons. • In some digital signature systems, a party attests to a document by publishing a public key signature … See more
