Title:
Key Committing AEADs
Authors: Shay Gueron
Abstract:This note describes some methods for adding a key commitment property to a generic (nonce-based) AEAD scheme. We analyze the the privacy bounds and key commitment guarantee of the resulting constructions, by expressing them in terms of the properties of the underlying AEAD scheme and the added key commitment primitive. We also offer concrete constructions for a key committing version of AES-GCM.
