WebApr 12, 2024 · Hashing uses an algorithm to translate data of any size to a fixed length, resulting in a hash value, rather than the ciphertext produced by encryption algorithms. Hashing is used to verify that data has not been altered … WebWe describe a hashing function from the elements of the finite field \mathbb {F}_q into points on a Hessian curve. Our function features the uniform and smaller size for the cardinalities of almost all fibers compared with the other known hashing functions for elliptic curves.

Prominent examples of cryptosystems that hash to elliptic curves include Simple Password Exponential Key Exchange [ J96 ], Password Authenticated Key Exchange [ BMP00 ], Identity-Based Encryption [ BF01] and Boneh-Lynn- Shacham signatures [ BLS01 ].
WebThe elliptic curve only hash (ECOH)algorithm was submitted as a candidate for SHA-3 in the NIST hash function competition. However, it was rejected in the beginning of the competition since a second pre-image attackwas found. The ECOH is based on the MuHASHhash algorithm, that has not yet been successfully attacked.
