Partial abstract: We introduce ‘PROTECT’ a Platform for Robust Threshold Cryptography. It’s a freely available open-source project [1], and it can be readily deployed to implement a number of threshold-secure services. PROTECT implements cryptographic functionality as operations on shares of a physically distributed key. The implementation is robust in the sense that it tolerates and recovers from Byzantine faults, while preserving availability and confidentiality of the shared secret through share recovery and proactive share renewal operations.
