Foundations of security for hash chains in ad hoc networks
23rd International Conference on Distributed Computing Systems Workshops, 2003. Proceedings., 2004Nodes in ad hoc networks generally transmit data at regular intervals over long periods of time. Recently, ad hoc network nodes have been built that run on little power and have very limited memory. Authentication is a significant challenge in ad hoc networks, even without considering size and power constraints.

A hierarchical two-tier one-way hash chain protocol for secure internet transactions
Global Communications Conference, 2012One-way hash chains are a popular cryptographic technique used in many security applications. In this paper, we present a two-tier one-way hash chain (TTOHC) protocol to secure cookie-based Internet transactions.

A Novel Self-Renewal Hash Chain and Its Implementation
2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing, 2008Hash 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.

A multi-phase key pre-distribution scheme based on hash chain
International Conference on Fuzzy Systems and Knowledge Discovery, 2012Wireless sensor networks (WSNs) are usually deployed in the work area for a long time, but most key managements are not stable enough that brings great threats to the WSNs.

Improved Scalable Hash Chain Traversal
2003Yaron Sella recently proposed a scalable version of Jakobsson’s algorithm to traverse a hash chain of size n. Given the hash chain and a computation limit m (k=m+1 and \(b=\sqrt[k]{n}\)), Sella’s algorithm traverses the hash chain using a total of kb memory. We improve the memory usage to k(b-1).

A novel sender authentication scheme based on hash chain for Vehicular Ad-Hoc Networks
IEEE Symposium on Wireless Technology and Applications, 2011Vehicular ad hoc networks (VANETs) are receiving enormous research attention in the wake of rising challenges of safe driving, and demand for infotainment services on the move. Information security in VANETs is a critical design issue, since public lives

Right Transfer Method Based on Double HASH Chain
Applied Mechanics and Materials, 2014This Paper analyzes security issues during the process of the right transfer, sums up the basic needs during the transfer and the defects of existing rights transfer, and puts forward the right transfer program based on double HASH chain, which achieves the transfer of the digital right under the control of HASH Distance and meta-rights.

A New Self-Updating Hash Chain Structure Scheme
2009 International Conference on Computational Intelligence and Security, 2009Self-Updating Hash Chain can be used extensively in many fields, such as one time password(OTP), signatures and authentication etc. In this paper, we propose a new self-updating hash chain based linear partition-combination algorithm (LPCA), which can share data into m parts and any part can’ t leak any information of data s. At a each exchange process,
