We simulate a user authentication from multiple biometircs in Python. To simulate it, we need an attribute based encryption ABE (FAME: Fast Attribute-based Message Encryption, CCS17), and a fuzzy extractor FE (Reusable fuzzy extractors for low-entropy distributions, EUROCRYPT16).

Accountable-Blockchain-Rewriting

This is the implementation of the policy-based chameleon hash function with black-box accountability PCHBA. We use PCHBA to secure blockchain rewriting, such that trapdoor holder may maliciously rewrite the blockchain without being identified.

Python

rewritableBlockchain

using java implements an immutable blockchain system that mimics basic functionalities of blockchain system, and a rewritable blockchain. Both of them are based on Proof of Work (PoW) consensus.
