An Alternative Diffie-Hellman Protocol

open access: yesCryptography, 2020
The Diffie−Hellman protocol, ingenious in its simplicity, is still the major solution in protocols for generating a shared secret in cryptography for e-trading and many other applications after an impressive number of decades.

Dynamic Multi-secret Sharing Scheme in Vector Space Without Trusted Center [PDF]

open access: yesJisuanji gongcheng, 2017
The existing secret sharing scheme in the vector space cannot achieve the secret share update or the dynamic addition and deletion of members,and it is hard to ensure the existence of trusted center,so a multi-secret sharing scheme without trusted center

Secret Sharing on Superconcentrator

open access: yesCoRR, 2023
We study the arithmetic circuit complexity of threshold secret sharing schemes by characterizing the graph-theoretic properties of arithmetic circuits that compute the shares. Using information inequalities, we prove that any unrestricted arithmetic circuit (with arbitrary gates and unbounded fan-in) computing the shares must satisfy superconcentrator ...

Ephemeral Secrets: Multi-Party Secret Key Acquisition for Secure IEEE 802.11 Mobile Ad Hoc Communication

open access: yesIEEE Access, 2020
Mobile ad hoc networks consist of wireless nodes and can be established quickly with minimal configuration and cost, because, they do not require any infrastructure in advance.

Renewable Multi-secret Sharing of Self-selecting Sub-secret [PDF]

open access: yesJisuanji gongcheng, 2016
The existing public verifiable multi-secret sharing schemes without trusted centers can not make sub-secrets self-selected and periodical renewable simultaneously.In order to solve the problem,a public verifiable and renewable multi-secret sharing scheme

An ECDLP-Based Verifiable Multi-Secret Sharing Scheme [PDF]

open access: yesMathematics Interdisciplinary Research, 2020
‎‎Secret sharing is an important issue in cryptography which has many applications‎. ‎In a secret sharing scheme‎, ‎a secret is shared by a dealer among several participants in such a way that any authorized subset of participants can recover the secret ...

On-line secret sharing [PDF]

open access: yesDesigns, Codes and Cryptography, 2011
In an on-line secret sharing scheme the dealer assigns shares in the order the participants show up, knowing only those qualified subsets whose all members she has seen. We assume that the overall access structure is known and only the order of the participants is unknown.

Verifiable multi-secret sharing schemes applicable to arbitrary access structures

open access: yesTongxin xuebao, 2007
Verifiable multi-secret sharing on general access structures was studied.A method of construct verifiable se-cret sharing schemes with arbitrary access structure was given.The verifiable multi-secret sharing schemes constructed by this method have the ...

Security of a kind of quantum secret sharing with entangled states

open access: yesScientific Reports, 2017
We present a new collusion attack to a kind of quantum secret sharing schemes with entangled states. Using this attack, an unauthorized set of agents can gain access to the shared secret without the others’ cooperation.

When are identification protocols with sparse challenges safe? The case of the Coskun and Herley attack

open access: yesJournal of Mathematical Cryptology, 2017
Cryptographic identification protocols enable a prover to prove its identity to a verifier. A subclass of such protocols are shared-secret challenge-response identification protocols in which the prover and the verifier share the same secret and the ...
