Formalising identity management protocols
No full textIn this paper we present the formalisation of three well-known Identity Management protocols - SAML, OpenID and OAuth. The formalisation consists of two steps: formal specification using HLPSL (High-Level Protocol Specification Language) and formal verification using a state-of-the-art verification tool for security protocols called AVISPA (Automated Validation of Internet Security Protocols and Applications). The existing formalisation initiatives using AVISPA are based on SAML and OpenID, leaving OAuth entirely, even though OAuth is one of the most widely-used Internet protocols. Furthermore, the motivation of the existing initiatives was to identify any weakness. In this paper, we have taken an opposite approach as we are keen to present how to model these protocols correctly. Moreover, our formalisation is based on a model of identity and also captures the authentication mechanism; both of these are missing in theexisting works

Friends of the Greenwood Library Presents Ron Smith
No full textVirginia Poet Laureate Ron Smith spoke and read at Longwood University April 14, 2015 in celebration of National Poetry Month.
Smith, a longtime professor and celebrated poet, is currently writer-in-residence at St. Christopher’s School in Richmond. He is the author of Running Again in Hollywood Cemetery, Moon Road and Its Ghostly Workshop. He will speak and read from his poetry on April 14 at 7 p.m. in the Greenwood Library atrium. The event is free and open to the public.
I’m excited to bring Ron Smith, poet laureate of the Commonwealth, to speak at Longwood during National Poetry Month, said Suzy Szasz Palmer, dean of Greenwood Library. Virginia is rich in its history but also in its depth of literary writers. Fiction and nonfiction typically garner more public attention, but it’s vitally important to celebrate the role of poetry in our culture. Virginia’s poet laureates serve for two-year terms, and Mr. Smith is the third poet laureate we’ve hosted since I came to Longwood in July 2011, thanks to the Friends of the Greenwood Library.
Many of Smith’s poems center on his time in college at the University of Richmond, where he played football on the Tangerine Bowl championship team. He also holds a master’s degree from VCU

A hybrid model of attribute aggregation in federated identity management
No full textThe existing model of Federated Identity Management (FIM) allows a user to provide attributes only from a single Identity Provider (IdP) per service session. However, this does not cater to the fact that the user attributes are scattered and stored across multiple IdPs. An attribute aggregation mechanism would allow a user to aggregate attributes from multiple providers and pass them to a Service Provider (SP) in a single service session which would enable the SP to offer innovative service scenarios. Unfortunately, there exist only a handful of mechanisms for aggregating attributes and most of them either require complex user interactions or are based on unrealistic assumptions. In this paper, we present a novel approach called the Hybrid Model for aggregating attributes from multiple IdPs using one of the most popular FIM technologies: Security Assertion Markup Language (SAML). We present a thorough analysis of different requirements imposed by our proposed approach and discuss how we have developed a proof of concept using our model and what design choices we have made to meet the majority of these requirements. We also illustrate two use-cases to elaborate the applicability of our approach and analyse the advantages it offers and the limitations it currently has
Towards a metric for recognition-based graphical password security
No full textRecognition-based graphical password (RBGP) schemes are not easily compared in terms of security. Current research uses many different measures which results in confusion as to whether RBGP schemes are secure against guessing and capture attacks. If it were possible to measure all RBGP schemes in a common way it would provide an easy comparison between them, allowing selection of the most secure design. This paper presents a discussion of potential attacks against recognition-based graphical password (RBGP) authentication schemes. As a result of this examination a preliminary measure of the security of a recognition-based scheme is presented. The security measure is a 4-tuple based on distractor selection, shoulder surfing,
intersection and replay attacks. It is aimed to be an initial proposal and is designed in a way which is extensible and adjustable as further research in the area develops. Finally, an example is provided by application to the PassFaces scheme
