Efficient Sparse Merkle Trees: Caching Strategies and Secure (Non-)Membership Proofs
Caching Strategies Secure (Non-)Membership Proofs
2016/7/13
A sparse Merkle tree is an authenticated data structure based on a perfect Merkle tree of intractable size. It contains a distinct leaf for every possible output from a cryptographic hash function, an...
Supporting Non-membership Proofs with Bilinear-map Accumulators
Non-membership Proofs Bilinear-map Accumulators RSA accumulator
2009/6/11
In this short note, we present an extension of Nguyen’s bilinear-map based accumulator scheme [8]
to support non-membership witnesses and corresponding non-membership proofs, i.e., cryptographic
pro...
