Can I use charm crypto tool to run it over my datasets for CPABE scheme and plot graphs using its Benchmarking tool ? Or, how can I use Charm Crypto tool with CPABE toolkit ?

1) Yes, you can use charm as a benchmarking tool for bandwidth performance, for CP-ABE, but not for computational performance, as charm is basically python over the PBC-library (https://crypto.stanford.edu/pbc/). We used charm for Dual-Policy ABE evaluation, but for subjective policies that becomes identical to CP-ABE, see http://dx.doi.org/10.1109/MILCOM.2016.7795382.

2) Bethencourt's cpabe toolkit and charm are actually parallel frameworks. You probably could tweak charm to use PBC via the cpabe toolkit, but there's no reason, as you can use PBC directly from charm as well (easier, in my opinion)

  • $\begingroup$ Can you explain me briefly how did you use charm for the benchmarking. **link to any demonstration could help me a lot $\endgroup$ – ut42 Mar 20 '17 at 9:54
  • $\begingroup$ Charm seems to be discussed in more detail in the stackoverflow, just google "Charm crypto site:stackoverflow.com", or add "cpabe" as a search term if too many hits (to have a detailed look at source code level). Our aims can be found from the DOI-link above (but no source code). $\endgroup$ – Mikko_K_123 Mar 23 '17 at 7:22
