# Secure logging from fault-tolerant aggregate signatures

## Information
This is a simple implementation of the logging system described in "Practical and Robust Secure Logging from Fault-Tolerant Sequential Aggregate Signatures" (International Conference on Provable Security, 2017, [also available from the IACR E-Print-Server](https://eprint.iacr.org/2017/949)).

## Disclaimer
This is an academic implementation used for benchmarking in the paper. Since this is the only purpose, this impelmentation is not well tested and reviewed for security and therefore should be used with caution.

## Used libraries
- Boost unit test framework
- [libpbc](https://crypto.stanford.edu/pbc/) with [pbcwrapper](https://crysp.uwaterloo.ca/software/PBCWrapper/)
- [NTL](http://www.shoup.net/ntl/)

## Build instructions
Make sure that boost, libpbc and NTL are installed. (The versions of libpbc and NTL used for the benchmarks reported in the paper can be found in the lib folder.) Then run:
```
mkdir build
cd build
cmake ..
make
```
pbcwrapper will be built automatically during this process.
