Abstract
-
Computational NMC against \({\mathsf {A}}{\mathsf {C}}^0\) tampering, in the CRS model, assuming a PKE scheme with decryption in \({\mathsf {A}}{\mathsf {C}}^0\) and NIZK.
-
Computational NMC against bounded-depth decision trees (of depth \(n^\epsilon \), where n is the number of input variables and constant \(0<\epsilon <1\)), in the CRS model and under the same computational assumptions as above.
-
Information theoretic NMC (with no CRS) against a streaming, space-bounded adversary, namely an adversary modeled as a read-once branching program with bounded width.
