A JSON Token-Based Authentication and Access Management Schema for Cloud SaaS Applications
Cloud computing is significantly reshaping the computing industry built
around core concepts such as virtualization, processing power, connectivity and
elasticity to store and share IT resources via a broad network. It has emerged
as the key technology that unleashes the potency of Big Data, Internet of
Things, Mobile and Web Applications, and other related technologies, but it
also comes with its challenges - such as governance, security, and privacy.
This paper is focused on the security and privacy challenges of cloud computing
with specific reference to user authentication and access management for cloud
SaaS applications. The suggested model uses a framework that harnesses the
stateless and secure nature of JWT for client authentication and session
management. Furthermore, authorized access to protected cloud SaaS resources
have been efficiently managed. Accordingly, a Policy Match Gate (PMG) component
and a Policy Activity Monitor (PAM) component have been introduced. In
addition, other subcomponents such as a Policy Validation Unit (PVU) and a
Policy Proxy DB (PPDB) have also been established for optimized service
delivery. A theoretical analysis of the proposed model portrays a system that
is secure, lightweight and highly scalable for improved cloud resource security
and management.Comment: 6 Page

Concept for Setting up the Persistent Identifier Services Working Group in the NFDI Section "Common Infrastructures"
The aim of this NFDI working group is to develop a common strategy for the implementation and extension of PID services that is closely aligned with the needs of NFDI consortia. Resulting solutions should enable FAIR research workflows balancing out generic metadata requirements for PIDs that maximise resource discoverability on the one hand and subject-specific needs on the other. At the technical level, the partners want to realise interoperability between PID types and established systems and build on a high level of maturity here; jointly developed services should be able to be rolled out for the entire NFDI
A UNICORE Globus Interoperability Layer
For several years, UNICORE and Globus have co-existed as approaches to exploiting what has become known as the ``Grid''. Both offer many services beneficial for creating and using production Grids. A cooperative approach, providing interoperability between Globus and UNICORE, would result in an advanced set of Grid services that gain strength from each other. This paper outlines some of these parallels and differences as they relate to the development of an interoperability layer between UNICORE and Globus. Given the increasing ubiquity of Globus, what emerges is the desire for a hybridised facility that utilises the UNICORE work-flow management of complex, multi-site tasks, but that can run on either UNICORE- or Globus-enabled resources. The technical challenge in achieving this, addressed in this paper, consists of mapping resource descriptions from both grid environments to an abstract format appropriate to work-flow preparation, and then the instantiation of work-flow tasks on the target systems. Other issues such as reconciling disparate security models and file transfer support are also addressed

Workshop on PIDs within NFDI: Report of the Working Group “Persistent Identifiers (PID)” of the Section Common Infrastructures of the NFDI
In order to gain an overview of the current state of the discussion on PIDs and for the identification of use cases for the initiation phase of a PID service within the NFDI basic services, the working group Persistent Identifier of the Section Common Infrastructures of the NFDI hosted an online workshop in January 2023. In the course of the workshop, members of nine different NFDI consortia presented the current application of PIDs in their consortia
Statins as antifungal agents
This poster paper describes the objectives, approach and use casesof the EC FP7 Integrated Project PERICLES. The project beganon 1st February 2013 and runs for four years. The aim is toresearch and prototype solutions for digital preservation incontinually evolving environments including changes in context,semantics and practices. The project addresses use cases focusingon digital art, media and science.Proceedings source: http://purl.pt/24107/1/iPres2013_PDF/iPres2013-Proceedings.pd
