Boolean functions form the backbone of modern cryptographic systems, serving as essential components in the design of stream ciphers, block ciphers, and other security protocols. Their inherent ...

By understanding how cryptographic hash functions work and the critical role they play, we can better appreciate the technology that underpins modern cybersecurity.

A cryptographic hash function combines the message-passing capabilities of hash functions with security properties. Hash functions are algorithms that determine how information is encrypted.

Unlike encryption algorithms, there are no secret keys involved; this makes it harder to mathematically define exactly what hash functions are.

Now cryptography and complexity have a shared goal, and each field offers the other a fresh perspective: Cryptographers have powerful reasons to think that one-way functions exist, and complexity ...

Author Nick Sullivan worked for six years at Apple on many of its most important cryptography efforts before recently joining CloudFlare, where he is a systems engineer. He has a degree in mathematics ...

This hash function, named “Troika,” was developed by CYBERCRYPT’s expert cryptographers, and will lay a strong cryptographic foundation for the final IOTA protocol.

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.
