Robust Threshold DSS Signatures
TLDR
This work presents threshold DSS (digital signature standard) signatures where the power to sign is shared by n players such that for a given parameter t there is a consensus that n players should have the right to sign.Abstract:
We present threshold DSS (digital signature standard) signatures where the power to sign is shared by n players such that for a given parameter tread more

Secure Distributed Key Generation for Discrete-Log Based Cryptosystems
TL;DR: This paper shows that a widely used dlog-based DKG protocol suggested by Pedersen does not guarantee a uniformly random distribution of generated keys, and presents a new protocol which proves to satisfy the security requirements from DKG protocols and ensures a uniform distribution of the generated keys.

Secure distributed key generation for discrete-log based cryptosystems
TL;DR: A distributed key generation protocol, that achieves optimal resiliency, can be used as a drop-in replacement for key generation modules as well as other components of threshold or proactive discrete-log based cryptosystems.
COCA: A Secure Distributed On-line Certification Authority
TL;DR: Traditional techniques, including request authorization, resource management based on segregation and scheduling different classes of requests, as well as caching results of expensive cryptographic operations further reduce COCA''.

A public key cryptosystem and a signature scheme based on discrete logarithms
TL;DR: A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem that relies on the difficulty of computing discrete logarithms over finite fields.

How to play ANY mental game
TL;DR: This work presents a polynomial-time algorithm that, given as a input the description of a game with incomplete information and any number of players, produces a protocol for playing the game that leaks no partial information, provided the majority of the players is honest.

A digital signature scheme secure against adaptive chosen-message attacks
TL;DR: A digital signature scheme based on the computational difficulty of integer factorization possesses the novel property of being robust against an adaptive chosen-message attack: an adversary who receives signatures for messages of his choice cannot later forge the signature of even a single additional message.
