Concurrent Chaining Hash Maps for Software Model Checking

2019 Formal Methods in Computer Aided Design (FMCAD), 2019
Stateful model checking creates numerous states which need to be stored and checked if already visited. One option for such storage is a hash map and this has been used in many model checkers. In particular, we are interested in the performance of concurrent hash maps for use in multi-core model checkers with a variable state vector size.

Self-Updating Hash Chains and Their Implementations

2006
Hash Chains are widely used in various cryptography applications such as one-time passwords, server-supported signatures and micropayments etc. However, the finite length (‘limited-link') of hash chains limits their applications. Some methods of re-initializing hash chains or infinite hash chains introduced in literatures are inefficient and un-smooth.

Data authentication for NDN using hash chains

2015 IEEE Symposium on Computers and Communication (ISCC), 2015
Named Data Networking (NDN) is considered to be a viable replacement of the traditional IP networking for the next generation Internet architecture. NDN is a data centric, rather than host centric, approach to discovery and retrieval of information distributed across a network.

A Recursive Algorithm for General Hash Chain Traversal

2014 IEEE 17th International Conference on Computational Science and Engineering, 2014
A hash chain is a popular tool for improving the efficiency of several cryptographic applications. In spite of the computation efficiency of one-way function, the performance issue is a challenging research topic for chains with long length in resource-constrained environments.

Analysis of hashing with chaining in the prime area

Journal of Algorithms, 1984
The expected performance of hashing with chaining in the prime area is analyzed. The basic idea of this overflow handling technique is straightforward: a record that does not fit into its home bucket, is placed in some other (non-full) bucket and connected to an overflow chain emanating from the home bucket.

Hash table collision resolution with direct chaining

Journal of Algorithms, 1989
Abstract The hash table method called direct chaining, wherein chains of items with the same hash function value are kept in a single table without recourse to an index table or a separate overflow area, is described. An explicitly linked free-space list is used which allows arbitrary insertion and deletion sequences to be done indefinitely with no ...

A Novel Self-Renewal Hash Chain and Its Implementation

2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing, 2008
Hash chains are widely used for entity authentication or data-origin authentication. However, finite length of a hash chain limits its implementations. A new kind of hash chain, called self-renewable hash chain (SRHC) is proposed, which achieves a hash chain self-renewing or re-initialization smoothly, securely throughout its usage.

Hash chain based strong password authentication scheme

2016 13th International Bhurban Conference on Applied Sciences and Technology (IBCAST), 2016
The constant influence of passwords over all other methods of identity authentication is a key discomfiture to security examiners. Web technologies are gaining more and more fame day by day but the persistent survival and replication of password authentication schemes generate difficulties for end users.
