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

Novel self-renewal hash chain scheme based on (t,n) threshold and division tree
The introduction of renewal hash chain overcame resource-constrained defect in traditional hash chains,but the existing renewable schemes had still held unsatisfactory performance especially on security and complexity.The definitions of repetition ...

Atomic Crosschain Transactions for Ethereum Private Sidechains
The Atomic Crosschain Transaction for Ethereum Private Sidechains protocol allows composable programming across permissioned Ethereum blockchains. It allows for inter-contract and inter-blockchain function calls that are both synchronous and atomic: if ...

Energy-Efficient Hash Chain Traversal
A hash chain H for a one-way hash function h(·) is a sequence of hash values , where vn is a secret value, vi is generated by vi=h(vi+1) for i=n-1,n-2,...,0 an0d v0 is a public value. A hash chain traversal algorithm T computes and outputs the hash chain H, returning vi in time period (called round) i for 1≤i≤n.

Fast parallel construction of variable-length Markov chains
Background Alignment-free methods are a popular approach for comparing biological sequences, including complete genomes. The methods range from probability distributions of sequence composition to first and higher-order Markov chains, where a k-th order ...

Differential Analysis of a Cryptographic Hashing Algorithm HBC-256
The article observes the new hashing algorithm HBC-256. The HBC-256 algorithm is based on the block cipher of the compression function CF (Compression Function) and produces a 256-bits hash value.

Efficient Constructions for One-way Hash Chains [PDF]
Abstract: "One-way chains are an important cryptographic primitive in many security applications. Lamport first proposed to use one-way chains for one-time password authentication [19]. Subsequently, researchers proposed one-way chains as a basic building block for digital cash, for extending the lifetime of digital certificates, for constructing one ...

Selective Location Blinding Using Hash Chains [PDF]
Location-based applications require a user's movements and positions to provide customized services. However, location is a sensitive piece of information that should not be revealed unless strictly necessary. In this paper we propose a procedure that allows a user to control the precision in which his location information is exposed to a service ...
