In this paper JHAE, an authenticated encryption (AE) mode, was presented based
on the JH hash mode. JHAE is an on-line and single-pass dedicated AE mode based on permutation
that supports optional associated data (AD). It was proved that this mode, based
on ideal permutation, achieved privacy and integrity up to O(2n=2) queries where the length
of the used permutation was 2n. To decrypt, JHAE did not require the inverse of its underlying
permutation and therefore saved area space. JHAE has been used by Artemia, one of the
CAESAR candidates.
