Automatic generation of optimal quantum key distribution protocols
Proceedings of the Genetic and Evolutionary Computation Conference, 2017Quantum 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

A novel proxy key generation protocol and its application
Computer Standards & Interfaces, 2007Proxy 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.

Excalibur Key-Generation Protocols for DAG Hierarchic Decryption
2019Public-key cryptograpy applications often require structuring decryption rights according to some hierarchy. This is typically addressed with re-encryption procedures or relying on trusted parties, in order to avoid secret-key transfers and leakages. Using a novel approach, Goubin and Vial-Prado (2016) take advantage of the Multikey FHE-NTRU encryption

SmokeGrenade: An Efficient Key Generation Protocol With Artificial Interference
IEEE Transactions on Information Forensics and Security, 2013Leveraging 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), 2007Proxy 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), 2016Smart 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.

The Generalized Diffie-Hellman Key Exchange Protocol on Groups
2017In 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.

ID-based secure key generation protocol
2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011), 2011Identity-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 ...

Secure Applications of Pedersen’s Distributed Key Generation Protocol
2003Secrecy of private signing keys is one of the most important issues in secure electronic commerce. A promising solution to this problem is to distribute the signing function among multiple parties. However, a threshold signature scheme typically assumes that the shared signing function can only be activated by a quorum number of parties, which is ...
