KiviHash-SHA3

Secure Hash Algorithm IP Core

(224/256/384/512)

KiviHash-SHA3 Overview 

The KiviHash-SHA-3 (secure hash algorithms) is a hardware accelerator for cryptographic hashing functions. It is an area efficient and high throughput design and compliant to NIST’s FIPS 202 standard. It supports all SHA-3 hash functions (SHA-3-224, SHA-3-256, SHA-3-384 and SHA-3-512) as well as extendable output functions (XOF), SHAKE-128 and SHAKE-256. It provides full protection against time-based side channel attacks (SCA). Automatic byte padding is included.  It operates in a single clock domain and has been extensively verified.
