High-throughput, area-efficient hardware SHA-3 cryptographic hashing engine, compliant to NISTS’s FIPS 180-4 and FIPS 202 standards. Supports all four fixed-length Hash Functions and both Extendable Output Functions (XOF).
A definition of the term "Secure Hash Algorithm" (SHA) is presented. It refers to a group of related cryptographic hash functions. It is mentioned that the most utilized SHA family is SHA-1 which is used in different security applications and protocols, including transport layer security (TLS...
Techniques are disclosed to enable efficient implementation of secure hash functions and/or stream ciphers. More specifically, a family of graphs is described that has relatively large girth, large cl

that the original message has not been altered during transmission. Hash functions are unkeyed cryptographic primitives which do not guarantee authenticity. They can be combined with a secret key to produce a message authentication code. They also serve as a cryptographic primitive used in digital.....
Examples of commonly used hash functions include checksum functions, cryptographic hash functions, and cyclic redundancy checks. Cryptography in Cybersecurity Computers communicate with each other daily via direct connections, which creates the need for strong data security. Modern-day applications of crypt...

Families of hash functions. We usually consider hash functions which map strings of arbitrary length into strings of a xed length. In some constructions we allow these functions to be randomized. Namely, we consider functions of the type h : $ f0; 1g ! f0; 1gk for some set of coins $...
