Nonuniform Indistinguishability and Unpredictability Hardcore Lemmas: New Proofs and Applications to Pseudoentropy
Hardcore Lemmas Pseudoentropy
2016/1/4
Using only the standard min-max theorem and some basic facts about convex approximations in Lp spaces, we provide alternative modular proofs and some generalizations of these results in the nonuniform...
NEW PROOFS OF THE TORELLI THEOREMS FOR RIEMANN SURFACES
NEW PROOFS THE TORELLI THEOREMS RIEMANN SURFACES
2018/4/19
In this paper, by using the Kuranishi coordinates on the Teichm¨uller spaceand the explicit deformation formula of holomorphic one-forms on Riemann surface, we
give an explicit expression of the peri...
We study the standard block cipher modes of operation: CBC, CFB, and OFB
and analyse their security. We don’t look at ECB other than briefly to note its insecurity,
and we have no new results on cou...
New Proofs for NMAC and HMAC: Security Without Collision-Resistance
Message authentication hash functions Pseudorandom Functions Carter-Wegman
2008/10/27
HMAC was proved in [3] to be a PRF assuming that (1) the underlying compression function
is a PRF, and (2) the iterated hash function is weakly collision-resistant. However, recent attacks
show that...
