This work describes schemes for distributing between n servers the evaluation of a function f
which is an approximation to a random function, such that only authorized subsets of servers …

A key distribution scheme for dynamic conferences is a method by which initially an (off-line)
trusted server distributes private individual pieces of information to a set of users. Later any …

Abstract A Distributed Key Generation (DKG) p rotocol is an essential component of any
threshold cryptosystem. It is used to initialize the cryptosystem and generate its private and …

Assume that it should be possible to protect messages transmitted in a N-user network by
encryption. The encryption can either be performed by a public-key crypto system or by a …

Key distribution is a major cryptographic component for secure communication. For privacy
data must be encrypted with keys which are distributed securely. In this paper we focus on …

In this paper we analyze perfectly secure key distribution schemes for dynamic conferences.
In this setting, anymember of a group oftusers can compute a common key using only his …

This paper provides an exposition of methods by which a trusted authority can distribute
keys and/or broadcast a message over a network, so that each member of a privileged …

Distributed key generation is a main component of threshold cryptosystems and distributed
cryptographic computing in general. Solutions to the distributed generation of private keys …

We survey the paradigms, approaches and techniques used to conceptualize, define and
provide solutions to natural cryptographic problems. We start by presenting some of the …

Encryption is used in a communication system to safeguard information in the transmitted
messages from anyone other than the intended receiver (s). To perform the encryption and …
