It is sometimes required that user pairs in a network share secret information to be used for mutual identification or as a key in a cipher system. If the network is large it becomes impractical or even impossible to store all keys securely at the users. A natural solution then is to supply each user with a relatively small amount of secret data from which he can derive all his keys. A scheme for this purpose will be presented and we call such a scheme a symmetric key generation system (SKGS… Expand

The topical problem of the key distribution in a community for providing secure communication among its participants is studied. To solve this problem, key predistribution systems can be considered,Expand
On optimal cryptographic key derivation
A provably secure key derivation scheme based on pseudorandom functions is given, along with an algorithm to find the optimal key linking pattern for any given access structure, which demonstrates the theoretic limit of any systems which do not trade off security. Expand
Perfectly-secure Dynamic-conference Key Distribution Extended Abstract
    A conference key (key) distribution scheme is a method to distribute some pieces of information among a set of users is such a way each group (pair) of users can compute a common key to use forExpand

    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 subset of users canExpand
    A unified model for unconditionally secure key distribution
    This paper presents a model for unconditionally secure key distribution schemes, i.e., schemes whose security is independent of the power of the adversary, and proves lower bounds on the amount of information the trusted party has to generate and each user has to keep secret in such schemes.

    A Probabilistic Key Agreement Scheme for Sensor Networks without Key Predistribution
    This paper gives and theoretically analyze a series of protocols that enables two entities that have never encountered each other before to establish a shared piece of information for use as a key in setting up a secure communication session with the aid of a shared key encryption algorithm.

    An ID-based cryptographic mechanisms based on GDLP and IFP
    An ID-based cryptosystem under the security assumptions of the generalized discrete logarithm problem and integer factorization problem and the possibility of establishing a more secure system is proposed. Expand
    Threshold Password-based Authenticated Key Exchange using Matrix
    Two new protocols are presented: client-server protocol and three-party protocol based on the Blom’s scheme, which don’t require the RSA assumption or Diffie-Hellman messages and have a threshold property and have to use two secret values. Expand

    • 2003
    A new construction of a key predistribution scheme using a family of vector space secret sharing schemes is presented and it is shown that a particular case of this construction is any key predistsribution scheme in which pieces of information and secrets are linear combinations of random numbers. Expand
    Generalised key distribution patterns
    Methods from set theory and ideas from convex analysis are used in order to construct general structures and provide some mathematical insight into their behaviour and analyse these general structures by exploiting the proof techniques of other authors in new ways, tightening existing inequalities and generalising results from the literature.
