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, ...

Construction and Traversal of Hash Chain with Public Links
Traversal Hash Chain Public Links
2009/4/3
Current hash chain traversal techniques require that the intermediate links of the
hash chain be stored secretly on a trusted storage. This requirement is undesirable
in several applications. We pro...
Hash Chains are used extensively in various cryptographic systems such as onetime
passwords, server supported signatures, secure address resolution, certificate
revocation, micropayments etc. Howeve...
