Ristenpart et al. (EUROCRYPT 2011) showed that the indifferentiability theorem of Maurer et al. (TCC 2004) does not cover all multi-stage security notions; it only covers single-stage security notions. They defined reset indifferentiability, and proved the reset indifferentiability theorem, which covers all security notions; if a hash function is reset indifferentiable from a random oracle denoted by RO, for any security, any cryptosystem is at least as secure under the hash function as in the RO model. Unfortunately, they also proved the impossibility of one-pass hash functions such as ChopMD and Sponge; there exists a multi-security notion such that some cryptosystem is secure in the RO model but insecure when RO is replaced with a one-pass hash function.
