Enhancing 802.11i key distribution using quantum key distribution
International Journal of Applied Research on Information Technology and Computing, 2011Security of data is one of the most important factors to take into account while elaborating any information system, especially when the information is transmitted over a wireless network like one of a company, a factory, a campus, or more importantly a battlefield.

On the Distribution of a Key Distribution Center
2001A Key Distribution Center of a network is a server who generates and distributes secret keys used by groups of users to securely communicate. A Distributed Key Distribution Center is a set of servers that jointly realizes a Key Distribution Center. In this paper we study Distributed Key Distribution Centers, pointing out the advantages of this approach

2009 Fifth International Conference on Signal Image Technology and Internet Based Systems, 2009
We first review and compare private key distributions in MANETs based on secret sharing schemes. Since there exist many kinds of networks with different objectives and constraints, we then determine the suitable private key distribution scheme according to the nature of the network.

Communication in key distribution schemes
IEEE Transactions on Information Theory, 1996Summary: A \((g,b)\) key distribution scheme allows conferences of \(g\) users to generate secret keys, such that disjoint coalitions of \(b\) users cannot gain any information on the generated key (in the information-theoretic sense). In this work, we study the relationships between communication and space efficiency of key distribution schemes.

On the distribution of keys by hashing
12th International Conference of the Chilean Computer Science Society, 2002. Proceedings., 2003The distribution of keys by a hash function as used in hash search with chaining is studied by considering the distribution of keys a random function front keys to buckets would give. This model gives surprisingly simple expressions for the mean value of some statistics on hash functions.

A conference key distribution system
IEEE Transactions on Information Theory, 1982Encryption 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 decryption the transmitter and receiver(s) ought to have matching encryption and decryption keys.

Quantum Key Distribution [PDF]
, 2010 In this chapter a complete QKD protocol is presented, starting from the transmission via the quantum channel up to the communication over the public channel. The protocol described here is the BB84 protocol, named after Bennett and Brassard [5]. There are other protocols like the B92 protocol [3], the six-state protocol [8], the SARG protocol [19] and ...

Zero Knowledge (ZK) theory formed the basis for practical identification and signature cryptosysems (invented by Fiat and Shamir). It also was used to construct a key distribution scheme (invented by Bauspiess and Knobloch); however, it seems that the ZK concept is less appropriate for key distribution systems (KDS), where the main cost is the number ...

Conventional implementations of cryptography are only computationally secure. The security of quantum cryptography (QC), on the other hand, is based on the inherent uncertainty in quantum phenomena at the physical layer of a communication system.
