An Ordered Universal Accumulator Based on a Hash Chain
Applied SciencesCryptographic accumulators are now fundamental for secure applications across blockchain, IoT, and big data, powering anonymous credentials, streamlining key management, and enabling efficient data filtering. However, existing accumulator methods, like RSA, bilinear pairing, and Merkle trees, are hampered by storage bloat, computational burdens, and ...

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 ...

Selective Location Blinding Using Hash Chains [PDF]
, 2011 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 ...

CHAIN: Exploring Global-Local Spatio-Temporal Information for Improved Self-Supervised Video Hashing [PDF]
, 2023 Compressing videos into binary codes can improve retrieval speed and reduce storage overhead. However, learning accurate hash codes for video retrieval can be challenging due to high local redundancy and complex global dependencies between video frames, especially in the absence of labels.

Individual Displacements in Hashing with Coalesced Chains [PDF]
Combinatorics, Probability and Computing, 2008 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.

Migration mechanism of heterogeneous memory pages using a two-way Hash chain list [PDF]
Scientia Sinica Informationis, 2019 With the rapid development of big data technologies, the requirements of tremendously accessing memory are increasing, therebyresulting in a serious problem of high consumption power by accessing traditional DRAM memory.
