A generic multicast-key determination protocol

Proceedings of IEEE Singapore International Conference on Networks/International Conference on Information Engineering '93, 2002
This paper examines a generic deadlock-free protocol for the automated maintenance of a commonly-shared multicast-key within a group in communication with each other. The protocol's use under conditions of both centralized and distributed controls is described.

A novel proxy key generation protocol and its application

Computer Standards & Interfaces, 2007
Proxy signature is an important technology in secure e-commerce. Short signature and fast verification are of paramount importance for its practical application. In this paper, we propose a proxy signature key generation protocol in which the warrant is the proxy public key for the first time.

Automatic generation of optimal quantum key distribution protocols

Proceedings of the Genetic and Evolutionary Computation Conference, 2017
Quantum Key Distribution (QKD) allows two parties to establish a shared secret key secure against an all-powerful adversary. Typically, one designs new QKD protocols and then analyzes their maximal tolerated noise mathematically. If the noise in the quantum channel connecting the two parties is higher than this threshold value, they must abort. In this

Distributed Key Generation as a Component of an Integrated Protocol

2002
In this paper we discuss the security issue of distributed key generation in a distributed threshold protocol. We identify two subtle flaws in the previously proposed discrete-log based distributed key generation protocols. We propose a discrete-log based distributed key generation protocol that meets the necessary security requirements and has no such

SmokeGrenade: An Efficient Key Generation Protocol With Artificial Interference

IEEE Transactions on Information Forensics and Security, 2013
Leveraging a wireless multipath channel as the source of common randomness, many key generation methods have been proposed according to the information-theory security. However, existing schemes suffer a low generation rate and a low entropy, and mainly rely on nodes' mobility.

Security enhancement of a novel proxy key generation protocol

31st Annual International Computer Software and Applications Conference - Vol. 2 - (COMPSAC 2007), 2007
Proxy signature is a variant of digital signature, in which the proxy signer could sign message on behalf of the original signer. In 2007, Hu et al. introduced a mechanism into the proxy signature model to allow rebuilding the short-term proxy key in a very efficient way.

Secure key generation and distribution protocol for wearable devices

2016 IEEE International Conference on Pervasive Computing and Communication Workshops (PerCom Workshops), 2016
Smart wearable devices have enormous applications in today's world and hence their usage is increasing significantly. As these devices communicate using wireless medium, the communication must be protected from eavesdropping by using shared secret keys for data encryption.

ID-based secure key generation protocol

2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011), 2011
Identity-based Cryptography (IBC) is an exciting alternative to public-key Cryptography (PKC), as it eliminates the need for certificate that is a major issue in PKC. However, IBC suffers from an additional limitation viz. the key escrow problem — that is — a user's private key is generated by the central trusted Key Generation Centre (KGC) — that ...

SmokeGrenade: A Key Generation Protocol with Artificial Interference in Wireless Networks

2013 IEEE 10th International Conference on Mobile Ad-Hoc and Sensor Systems, 2013
Leveraging a wireless multi-path channel as a source of common randomness, a number of key generation methods have been proposed according to information-theory security. However, by taking the advantages of node's mobility, existing schemes usually have low generation rate or low entropy.

The Generalized Diffie-Hellman Key Exchange Protocol on Groups

2017
In this paper, we study key exchange protocol which is similar to Diffie-Hellman key exchange protocol. This key exchange protocol uses maximal abelian subgroup of automorphism of group. We give an example group is used for key exchange protocol.
