DeCoTa: a lightweight decentralized cross-chain transfer scheme based on hash-locking [PDF]
Scientific ReportsWith the wide application of blockchain comes the challenge of cross-chain interaction. For example, the isolation between the information stored in different blockchains can result in the ”isolated islands of value” effect in blockchains.

Permutation-Based Hash Chains with Application to Password Hashing [PDF]
IACR Transactions on Symmetric CryptologyHash chain based password systems are a useful way to guarantee authentication with one-time passwords. The core idea dates back to Lamport, and is specified in RFC 1760 as S/Key. At CCS 2017, Kogan et al.

Efficient Constructions for One-way Hash Chains [PDF]
, 2003 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 ...

Individual displacements in hashing with coalesced chains [PDF]
Combinatorics, Probability and Computing, 2005 We study the asymptotic distribution of the displacements in hashing with coalesced chains, for both late-insertion and early-insertion. Asymptotic formulas for means and variances follow. The method uses Poissonization and some stochastic calculus.
