Abstract: In one set of embodiments, a computer system can initialize a counter that is shared by a plurality of software processes, where each software process is programmed to increment the counter a predefined number of times. The computer system can further run the plurality of software processes concurrently. Upon completion of the plurality of software processes, the computer system can apply one or more functions to the shared counter and output the result as an entropy sample.

Abstract: Techniques for implementing distributed registration and authentication (i.e., the collaborative processing of client registration and authentication requests by multiple nodes in a computing system) via threshold secret sharing are provided. A threshold secret sharing scheme is a cryptographic method for sharing a secret among N parties in a manner that requires at least T+1 of the N parties to cooperate in order to reconstruct/reveal the secret, where T is some threshold value less than N. By leveraging threshold secret sharing, these techniques enable a group of N nodes to efficiently implement distributed registration and authentication in a correct, secure, and privacy-preserving fashion, even if up to T of the N nodes are corrupted by an adversary.
