  • Pasarella Sánchez, Ana Edelmira; Lobo, Jorge (ACM Association for Computer Machinery, 2017)
    Relationships like friendship to limit access to resources have been part of social network applications since their beginnings. Describing access control policies in terms of relationships is not particular to social ...
  • Schaeffer-Filho, Alberto; Lupu, Emil; Sloman, Morris; Keoh, Sye-Loon; Lobo, Jorge; Calo, Seraphin (Springer, 2008)
    This paper addresses the problem of specifying and establishing secure collaborations between autonomous entities that need to interact and depend on each other in order to accomplish their goals. We call such collaborations ...
  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Universitat Pompeu Fabra, 2017)
    Network Function Virtualization (NFV) proposes to move packet processing from dedicated hardware middle-boxes to software running on commodity servers: virtualized Network Function (NFs) (i.e, Firewall, Proxy, Intrusion ...
  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (2017)
    To conduct a more realistic evaluations on resource allocation algorithms for Virtualized Network Functions (VNFs), researches need data on: (1) potential Network Functions (NFs) chains (policies), (2) traffic flows ...
  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Network Function Virtualization (NFV) is bringing closer the possibility to truly migrate enterprise data centers into the cloud. However, for a Cloud Service Provider to offer such services, important questions include ...
  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    With the introduction of network function virtualization technology, migrating entire enterprise data centers into the cloud has become a possibility. However, for a cloud service provider (CSP) to offer such services, ...
  • Pasarella Sánchez, Ana Edelmira; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    In this paper we show that the logical framework proposed by Becker et al. [1] to reason about security policy behavior in a trust management context can be captured by an operational framework that is based on the language ...
  • Rullo, Antonino; Serra, Edoardo; Bertino, Elisa; Lobo, Jorge (Springer, 2017)
    We present a method for computing the best provisioning of security resources for Internet of Things (IoT) scenarios characterized by a high degree of mobility. The security infrastructure is specifed by a security ...
  • Rankothge, Windhya; Ma, Jiefei; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    By allowing network functions to be virtualized and run on commodity hardware, NFV enables new properties (e.g., elastic scaling), and new service models for Service Providers, Enterprises, and Telecommunication Service ...
  • Rankothge, Windhya (Universitat Pompeu Fabra, 2017-04-06)
    Network Function Virtualization (NFV) is a promising technology that proposes to move packet processing from dedicated hardware middle-boxes to software running on commodity servers. As such, NFV brings the possibility of ...
  • Calvanese, Diego; Montali, Marco; Lobo, Jorge (CEUR Workshop Proceedings, 2018)
    Logic-based languages, such as Datalog and Answer Set Programming, have been recently put forward as a data-centric model to specify and implement network services and protocols. This approach provides the basis ...
