Cryptographic constructions are often designed and analyzed in idealized frameworks such as the random-oracle, public-permutation, or ideal-cipher models. In this work, I focus on the ideal cipher model where the block cipher is modeled as the ideal cipher and ask the following questions: (1) how to construct an ideal cipher and (2) how to reason about security of a block cipher-based construction that is instantiated with a "defective" ideal cipher. I discuss approaches to solving these two problems and propose research directions aimed at understanding the security provided by current approaches to block cipher designs.
