Novel self-renewal hash chain scheme based on (t,n) threshold and division tree
Tongxin xuebao, 2013 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 ...

Regional Science Policy &Practice, EarlyView., 2022 Abstract The agri‐food supply chain has been a popular research topic in recent years. The combination of a demand for products of high quality and safety standards and the increasing number of stakeholders in supply chain networks has required the agri‐food business to transform from vertically integrated to vertically operated supply chain networks ...

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 ...

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells
FEBS Open Bio, EarlyView.Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

A Secure Cooperative Sensing Protocol for Cognitive Radio Networks [PDF]
, 2010 Cognitive radio networks sense spectrum occupancy and manage themselves to operate in unused bands without disturbing licensed users. Spectrum sensing is more accurate if jointly performed by several reliable nodes. Even though cooperative sensing is an

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 ...
