Incompressibility is one of the most fundamental security goals in white-box cryptography.
Given recent advances in the design of efficient and incompressible block ciphers such as SPACE, SPNbox and WhiteBlock,
we demonstrate the feasibility of reducing incompressible AEAD modes to incompressible block ciphers.
We first observe that several existing AEAD modes of operation, including CCM, GCM(-SIV), and OCB, would be all …
