A Many-to-Many Decentralized Anonymous Data Sharing

This is the Sage-Python implementation of the protocol proposed in the paper A Many-to-Many Decentralized Anonymous Data Sharing Scheme proposed by E. Gunsay, B.E. Karakas, G. Orhon Kilic, and Oguz Yayla.

• Source files are located in src/.
• ds_bench_single.sage gathers the benchmarks for single operations: Signature generation, traceability check, collecting related signature files to verify a signature, and signature verification.
• ds_bench.sage gets the benchmarks for block generation and signature verification.
• ds_profiling_single.sage collects the profiling statistics for single operations.
• ds_profiling_full.sage collects the profiling statistics for block generation and signature verification.
• ds_test.sage runs full protocol.
• Tests are running for 256 signers.
• Run the profiling and bench scripts with

sage [your_file_name].sage [8/16/32/64/128]

where argv[1] is the ring size.

• Note that the scripts work with the ring size of the form $2^n$.
• Bench and profiling outputs are saved in results/.
• See paper for protocol details.
