An Alternative Diffie-Hellman Protocol
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]
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
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 ...

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

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
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
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.

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 ...
