Lightweight selective disclosure for verifiable documents on blockchain
ICT Express, 2021 To achieve lightweight selective disclosure for protecting privacy of document holders, we propose an XML format for documents that can hide arbitrary elements using a cryptographic hash function and salts, which allows to be partially digitally signed ...

Efficient asynchronous accumulators for distributed PKI [PDF]
, 2016 Cryptographic accumulators are a tool for compact set representation and secure set membership proofs. When an element is added to a set by means of an accumulator, a membership witness is generated. This witness can later be used to prove the membership
