Cryptographic sponge functions
WebMar 11, 2024 · Practically, both are considered cryptographically secure. So, when wanting arbitrary length of output, you'll have to decide what sponge function you want to use. Looking at Gimli, I'ld like to note that there are other sponge functions out there which are suitable for cryptographic purposes too.

WebA cryptographic function that applies a process on the input that has been padded with additional characters until all characters are used. (recently introduced) What are three broad categories of cryptographic algorithms. These are known as hash algorithms, symmetric cryptographic algorithms, and asymmetric cryptographic algorithms. WebA sponge function is a cryptographic function that can “absorb” any number of bits and “squeeze” any number of bits, like a sponge. This is different from what we observed about MD5; while MD5 will only produce fixed-size outputs of 16 bytes, a sponge function can output 1 byte, 26 bytes, 5000 bytes or any number that you like.
WebMar 20, 2024 · In section 3.2 "Modes of use of sponge functions" of Cryptographic Sponge Functions (CSF for short for the purpose of this answer), the authors listed several "modes of operations" for different purposes, with stream cipher applications being one of them. Here's the table: WebMar 28, 2024 · The sponge construction consists of two main components: The state: This is a fixed-size array of bits, often visualized as a grid of squares, where each square holds a single bit. The state is...
WebSponge functions are versatile cryptographic primitives that can be used for hashing, message authentication code (MAC) computation, stream encryption, authenticated encryption, pseudo- random sequence generation and other applications. We refer to [6,5,7] for description of such modes of use. A sponge function consists of the application of ... WebThis paper proposes spongent – a family of lightweight hash functions with hash sizes of 88 (for preimage resistance only), 128, 160, 224, and 256 bits based on a sponge construction instantiated with a present-type permutation, following the hermetic sponge strategy.Its smallest implementations in ASIC require 738, 1060, 1329, 1728, and 1950 GE, respectively.
A sponge function is built from three components: a state memory, S, containing b bits,a function $${\displaystyle f:\{0,1\}^{b}\rightarrow \{0,1\}^{b}}$$a padding function P S is divided into two sections: one of size r (the bitrate) and the remaining part of size c (the capacity). These sections are denoted R and C … See more In cryptography, a sponge function or sponge construction is any of a class of algorithms with finite internal state that take an input bit stream of any length and produce an output bit stream of any desired length. … See more Sponge functions have both theoretical and practical uses. In theoretical cryptanalysis, a random sponge function is a sponge construction where f is a random permutation or … See more
