Abstract: This paper considers the basic question of how strong of a probabilistic guarantee can a hash table, storing $n(1+\Theta(1))\log n$-bit key/value pairs ...

These functions take digital files as their input and generate relatively short alphanumeric codes called hash values, a.k.a. message digests, that are then attached to the files for security purposes ...

In the realm of computer science, it’s hard to go too far without encountering hashing or hash functions. The concept appears throughout security, from encryption to password storage to crypto, and ...

Vitalik Buterin has called on researchers to join the Poseidon cryptographic analysis program as Ethereum explores the potential switch to the Poseidon hash function to enhance its zk-proof ...

Computing practitioners encounter hash functions almost every day, although they may not necessarily be the center of attention. When you install software packages or updates, the authenticity of a ...

Cryptography, a cornerstone of modern information security, encompasses a vast array of techniques and tools designed to protect sensitive data from unauthorized access and tampering. Within this ...

Highly portable C system library: threads and synchronization primitives, sockets (TCP, UDP, SCTP), IPv4 and IPv6, IPC, hash functions (MD5, SHA-1, SHA-2, SHA-3, GOST ...
