Definition 2.1Cryptographic Hash Function A cryptographichash functionH:{0,1}∗→{0,1}nthat maps bit sequences of arbitrary length ton-bit outputs, withn∈N, satisfies the following properties: 1. For allx∈{0,1}∗it is computationally easy to calculatey=H(x). ...
A definition of the term "Cryptographic Hash Function" is presented. It refers to a mathematical function that generates a fixed-size result from arbitrary amounts of data. Cryptographic hash function is often called hash function.doi:US20140019747 A1Frederic P. Miller...
Cryptographic Hash Function A hash function H accepts a variable-length block of data as input and produces a fixed-size hash value h = H(M). The principal object of a hash function is data integrity. A change to any bit or bits in M results, with high probability, in a change to ...

By using the pre-shared secret key, the sender will create a MAC with a pre-decided hash function. The sender will then append the MAC to the message and transmit it to receiver(s). On receiving the message, each receiver will perform the same hash function on the message using the ...
Cryptographic hash functions are widely used incryptocurrenciesto pass transaction information anonymously. For example,Bitcoin, the original and largest cryptocurrency, uses the SHA-256 cryptographic hash function in its algorithm.1Ethereum, the second most popular blockchain, uses Keccak-256 to hash in...
