On the impossibility of entropy reversal, and its application to zero-knowledge proofs
statistical zero-knowledge proof entropy reversal black-box reduction
2017/9/25
Zero knowledge proof systems have been widely studied in cryptography. In the statistical setting, two classes of proof systems studied are Statistical Zero Knowledge (SZK) and Non-Interactive Statist...
Explicit Optimal Binary Pebbling for One-Way Hash Chain Reversal
hash chains pebbling in-place algorithms
2016/1/23
We present explicit optimal binary pebbling algorithms for reversing one-way hash chains. For a hash chain of length 2k , the number of hashes performed in each output round does not exceed dk/2e, ...
