JHAE: A Novel Permutation-Based Authenticated Encryption Mode Based on the Hash Mode JH
Author(s):
Abstract:
Authenticated encryption (AE) schemes provide both privacy and integrity of data. CAESAR is a competition to design and analysis of the AE schemes. An AE scheme has two components: a mode of operation and a primitive. In this paper JHAE, a novel authenticated encryption mode, is presented based on the JH (SHA-3 finalist) hash mode. JHAE is an on-line and single-pass dedicated AE mode based on permutation that supports optional associated data (AD). It is proved that this mode, based on ideal permutation, achieves privacy and integrity up to O(2n/2) queries where the length of the used permutation is 2n. To decrypt, JHAE does not require the inverse of its underlying permutation and therefore saves area space. JHAE has been used by Artemia, one of the CAESARs first round candidates.
