[en] We present an efficient key wrapping scheme that uses a single public permutation as the basic element. As the scheme does not rely on block ciphers, it can be used on a resource-constrained device where such a permutation comes from an implemented hash function, regular (SHA-3/Keccak) or lightweight one (Quark, Photon). The scheme is capable of wrapping keys up to 1400 bits long and processing arbitrarily long headers. Our scheme easily delivers the security level of 128 bits or higher with the master key of the same length.

We use the security notion from the concept of Deterministic Authenticated Encryption (DAE) introduced by Rogaway and Shrimpton. Though the permutation is inevitably modeled as a random permutation, the resulting proof of security is short and easy to verify and hence provide a reasonable alternative to authentication modes based on block ciphers
