Security and Privacy for Green IoT-based Agriculture: Review, Blockchain solutions, and Challenges

open access articleThis paper presents research challenges on security and privacy issues in the field of green IoT-based agriculture. We start by describing a four-tier green IoT-based agriculture architecture and summarizing the existing surveys that deal with smart agriculture. Then, we provide a classification of threat models against green IoT-based agriculture into five categories, including, attacks against privacy, authentication, confidentiality, availability, and integrity properties. Moreover, we provide a taxonomy and a side-by-side comparison of the state-of-the-art methods toward secure and privacy-preserving technologies for IoT applications and how they will be adapted for green IoT-based agriculture. In addition, we analyze the privacy-oriented blockchain-based solutions as well as consensus algorithms for IoT applications and how they will be adapted for green IoT-based agriculture. Based on the current survey, we highlight open research challenges and discuss possible future research directions in the security and privacy of green IoT-based agriculture

Climate Justice and Women's Rights: A Guide to Supporting Grassroots Women's Action

This Guide emerged from a "Summit on Women and Climate" in Bali, Indonesia, and aims to increase timely and appropriate funding for worldwide climate action initiatives led by women and their communities. The Guide is not a comprehensive resource on climate change or women's rights. Instead, it addresses an urgent need within the funding community and offers concrete, practical guidance that: Orients grantmakers to the importance of funding at the intersection of climate justice and women's rights.Draws lessons from specific examples of funding for women's climate change initiatives.Provides guidance on how funders can collaborate to direct timely and appropriate funding to women and their communities.Advocates for bringing women's voices into climate change policy discussions.Highlights the strong impact that small (less than $10,000) to medium-sized ($10,000-$50,000) grants can make in women-organized efforts to address climate change at the community level, across geographic boundaries and in global climate policy. Grassroots women's climate activism is becoming increasingly critical to women's collective and individual rights, freedom and survival

Exploiting Rateless Codes in Cloud Storage Systems

devices (virtual disks) that can be directly accessed and used as if they were raw physical disks. In this paper we devise ENIGMA, an architecture for the back-end of BLCS systems able to provide adequate levels of access and transfer performance, availability, integrity, and confidentiality, for the data it stores. ENIGMA exploits LT rateless codes to store fragments of sectors on storage nodes organized in clusters. We quantitatively evaluate how the various ENIGMA system parameters affect the performance, availability, integrity, and confidentiality of virtual disks. These evaluations are carried out by using both analytical modeling (for availability, integrity, and confidentiality) and discrete event simulation (for performance), and by considering a set of realistic operational scenarios. Our results indicate that it is possible to simultaneously achieve all the objectives set forth for BLCS systems by using ENIGMA, and that a careful choice of the various system parameters is crucial to achieve a good compromise among them. Moreover, they also show that LT coding-based BLCS systems outperform traditional BLCS systems in all the aspects mentioned before
