ARX-KW, a family of key wrapping constructions using SipHash and ChaCha

Satō Shinichi

Abstract

ARX-KW is a family of key wrapping construction based on add-rotate-xor primitives: the pseudo-random function SipHash for authentication and the stream cipher ChaCha for confidentiality. This paper presents ARX-KW, proposes a specific instantiation of ARX-KW and details the design decisions that were made.
